I don't get reassigned ever, but hey, there's the language plain as day.

Oh wait, there's more

Assignment or Reassignment After Loss of Flying, Training Assignment or Other Absence and Activity
20-F-1 Loss of Full Trip or Originating Segment of Trip
When a Pilot loses a full Trip or the originating portion thereof, due to a schedule repair, being out of position, cancellation, consolidation or Equipment substitution, regardless of whether he has reported for the Trip, he may be assigned or reassigned by the Company as follows:
20-F-1-a Prior to Scheduled Report Time. If he is advised of the loss of his flying prior to his scheduled report time for such flying, the Company shall at that time exercise one of the options below. A Pilot will be considered to be advised under this provision if two-way contact is established any time prior to Report Time or if the Company attempts to contact the Pilot and leaves messages describing the loss of flying at all provided contact phone numbers at least twenty-four (24) hours prior to Report Time. If however the loss of his flying is due to the suspension of operations at his Base, the Company shall exercise one of the following within two (2) hours after operations are resumed:
20-F-1-a-(1) Convert the day(s) on which the lost Trip was scheduled to operate to availability (“AV”) day(s). Until 1500 on the day prior to the first AV day, the Company may give him a flight assignment or assignments, including landings classes, recurrent training fill-in assignments, and additional flying to flight assignments already made, on that AV day(s). Assignments, once made, may only be removed with Pilot concurrence. For purposes of this paragraph, “lost Trip” refers to the Trip subset that is included in the Lineholder’s PTC.
20-F-1-a-(2) Require him to deadhead to any point to connect with the remainder of his scheduled assignment.
20-F-1-a-(3) If the loss of his flying occurs after 1300 on the day prior to the scheduled Departure of the Trip lost, require him to be telephone available for a period not to exceed
four (4) hours for a potential flight assignment. Such four (4) hour telephone availability period shall start no earlier than four (4) hours prior to the scheduled Departure time of the Trip lost and shall end no later than the scheduled release time of the Trip lost. In addition, the Pilot’s last Duty Period must have ended at least ten hours and forty-five minutes (10:45) before the start of the telephone availability period (or less, with Pilot concurrence).
20-F-1-a-(4) Give him a new assignment.
20-F-1-a-(5) Require him to report to the airport for a four (4) hour Field Standby assignment; such four (4) hour Field Standby assignment shall commence at the scheduled report time of the Trip he has lost.
20-F-1-a-(6) If the Pilot is a Reserve, give him a short-call reserve assignment that begins no earlier than the report time of the lost Trip.
20-F-1-a-(7) Relieve him from responsibility under the provisions of this Section 20-F. In such case, if the Pilot is a Reserve, he shall return to long-call.
20-F-1-a-(8) Any assignment given under this Section 20-F-1-a, including a deadhead to connect to the remainder of his scheduled assignment, cannot be scheduled to depart prior to 1800 or three (3) hours before the Pilot's originally scheduled Departure, whichever is earlier.
20-F-1-a-(9) If the lost flying was originally assigned under Section 20-H-5, the Add Pay the Lineholder received under those provisions shall be removed. Instead, the 100% Add Pay percentage he was entitled to under the original assignment shall apply to the scheduled pay value of the replacement Trip(s) he performs in conjunction with his obligation under Section 20-F-1-a. Section 20-L-6 shall not apply at the time of assignment of the replacement Trip(s), but it shall apply after that time.
20-F-1-a-(10) If the lost flying was originally assigned under Section 20-H-4, the Add Pay the Lineholder received under that provision shall be removed. Instead, the Add Pay percentage he was entitled to under the original assignment shall apply to the scheduled pay value of the replacement Trip(s) he performs in conjunction with his obligation under Section 20-F-1-a. If the Add Pay percentage he was entitled to under the original assignment is 100%, Section 20-L-6 shall not apply to such Lineholder. If such Add Pay percentage is seventy-five percent (75%), Section 20-L-6-a shall not apply and Section 20- L-6-b shall apply but at twenty-five percent (25%). If such Add Pay percentage is fifty percent (50%), Section 20-L-6-a shall not apply and Section 20-L-6-b shall apply without modification. The Add Pay limitations in this provision are in effect only at the time of assignment of the replacement Trip(s); after that time, there are no limitations on the applicability of Section 20-L-6.
20-F-1-a-(11) If a Reserve loses a full Trip, and if the assignment of the Trip involved a disruption to an RDO or VDO, the disrupted RDO or VDO will remain disrupted (i.e., as a reserve day), unless the Reserve elects to restore his schedule to how it existed before the
lost Trip was assigned. The Reserve must make such an election when he is advised of the loss of flying.
20-F-1-b After Scheduled Report Time. If he is advised of the loss of his flying at or after his scheduled report time for such flying or is not otherwise advised as provided in Section 20-F- 1-a, the Company shall exercise one of the following within two (2) hours of the time he is advised of the loss of his flying (in the event of a cancellation or Equipment substitution, the two (2) hours shall begin at the later of (1) the cancellation or Equipment substitution timestamp in the official system of record or (2) the Pilot’s report time); except that if the loss of his flying is due to the suspension of operations at his Base, the Pilot may be released from duty and the Company shall exercise one of the following within two (2) hours after operations are resumed:
20-F-1-b-(1) Require him to deadhead to any point to connect with the remainder of his scheduled assignment.
20-F-1-b-(2) Reassign him other flying within that Duty Period.
20-F-1-b-(3) Give him a new assignment after being given an Off-Duty Period of at least ten hours and forty-five minutes (10:45) (or less, with Pilot concurrence). This new assignment may not be a Field Standby assignment, without the Pilot’s concurrence.
20-F-1-b-(4) Require him to be telephone available for a period not to exceed four (4) hours for a potential flight assignment; the start time of such four (4) hour period shall be at least ten hours and forty-five minutes (10:45) (or less, with Pilot concurrence) after the Pilot is released from his current Duty Period.
20-F-1-b-(5) If the Pilot is a Reserve, require him to remain at the airport for a four (4) hour Field Standby assignment; such four (4) hour Field Standby assignment shall commence at the scheduled report time of the Trip he has lost.
20-F-1-b-(6) Relieve him from responsibility under the provisions of this Section 20-F. In such case, if the Pilot is a Reserve, he shall return to long-call.
20-F-1-c Any assignment or reassignment given a Pilot under the provisions of Sections 20-F- 1-a or 20-F-1-b must comply with the following limitations:
20-F-1-c-(1) It cannot be scheduled to interfere with the Pilot’s next scheduled day off. If a Reserve receives an assignment or reassignment under Section 20-F-1-b, it must also comply with Section 20-L.
20-F-1-c-(2) If it produces any new Off-Duty Periods at the Pilot's Base during the period of his original assignment, the Pilot shall, upon request, be provided a local hotel room.
20-F-1-c-(2)-(a) Until the Pilot actually reports, at a scheduled report time, whether for the canceled flying or for any assignment or reassignment, any additional off-duty time shall not be considered as a new Off-Duty Period and this provision shall not apply.
20-F-1-c-(3) If it is scheduled to interfere, or does interfere in the Actual Operation, with the Pilot's next scheduled Trip, the loss of such next Trip shall subject him to assignment or reassignment under this Section 20-F.
20-F-1-d If a Pilot is assigned an AV day, a telephone availability period, or Field Standby period, and is not utilized, the Pilot is relieved of responsibility under this Section 20-F-1.
20-F-1-e The Company may, at any time, split Open Trips to make flight assignments or reassignments under Section 20-F-1.
20-F-1-f When the originating segment of a Pilot’s Trip is canceled after a gate return or air return, this Section 20-F-1 shall apply.
20-F-1-g When applying Section 20-F-1-a or 20-F-1-b to an out-of-base Lineholder, he shall be assigned or reassigned as if he was an in-base Lineholder at the Base to which the out-of-base trip was assigned.

20-F-2 Loss of Segment After Originating Segment of Trip
When a Pilot loses any portion of a Trip other than the originating segment, regardless of whether he has reported for the Trip, he may be reassigned to other known Open Flying, including deadheading to such flying, in accordance with Section 20-L.
20-F-2-a A Pilot who is unable to return to his Base within the time limits set forth in Section 20-L as a result of the suspension of operations, either at his Base or at the airport at which he lost his scheduled flying, may, when operations are resumed, be reassigned to other known Open Flying which shall expediently return him to his Base, otherwise, he may be deadheaded to his Base. When this Section 20-F-2-a is applied by automation, ‘expedient’ shall mean no more than two Flight Segments and no intervening off-duty period.
20-F-2-b If the reassignment given above interferes with the Pilot's next scheduled Trip, the loss of such next scheduled Trip shall subject him to assignment or reassignment under Sections 20-F-1-a or 20-F-1-b.

20-F-3 Notwithstanding Sections 20-F-1 and 20-F-2, if a change to the applicable airline system schedule causes a Trip or trips to change, and, according to Sections 20-B-1 and 20-B-2, it is too late to include the changed Trips in Monthly Schedule Preferencing, the affected pilots may be assigned other flying as follows:
20-F-3-a The changes to lines of flying shall be limited to the fewest number of lines consistent with efficient scheduling and those affected pilots shall be notified as soon as possible after the changes are made.
20-F-3-b The primary effort shall be to assign the revised Trip on the same day(s) the Pilot(s) was scheduled to fly. No revised lines may exceed ninety (90) Line Credit hours.
20-F-3-c If an assignment produces any new Off-Duty Periods at the Pilot's Base during the period of his original assignment, the Pilot shall, upon request, be provided a local hotel room.
20-F-3-d A Pilot who is assigned a line with fewer Duty Periods than were contained in his original line may, at the time of initial notification of the revision, be given Section 20-F-1-a- (1) or 20-F-1-a-(3) assignments, as appropriate, on days he was originally scheduled to fly. The Company shall make such assignments available as far in advance as possible.
20-F-3-e Should the schedule change result in a reduction of flying at the Base equivalent to one Line of Flying or more, any Pilot who loses all of his flying may be assigned a reserve schedule which shall retain the days off he had in his original line.
20-F-3-fThe SSC shall be afforded the opportunity to consult with and make recommendations on schedule revisions.
20-F-3-g No more than five percent (5%) of Pilot schedules, as measured on a Category basis, shall be subject to assignment under this provision in any one Bid Period. Should an occasion arise which requires revision to more than five percent (5%) of schedules, all assignments must be made under the provisions of Section 20-F-1.
20-F-3-h Notwithstanding the five percent (5%) limit above, in the event of a major disruption to service outside of the Company's control (such as that created by the 1981 Air Traffic Controller's strike), the Company may revise schedules to the extent necessary to maintain the highest level of service possible. In such event, the Company shall work closely with the SSC to ensure that passenger schedule integrity is maintained without imposing unnecessary disruption on pilots' schedules.

20-F-4 When the Company cancels or terminates a training assignment of five (5) days or more that was included in Monthly Schedule Preferencing (excluding recurrent training), it shall be handled as follows:
20-F-4-a The Company shall construct an initial schedule based on the prorated duty days. On each work day, Lineholders may be assigned a period of telephone availability of four hours in duration, Field Standby or flying. Such assignments shall be made when the initial schedule is constructed. Reserves shall be given a prorated number of reserve days.
20-F-4-b Within seventy-two (72) hours of construction, the Pilot may contact the Company and rearrange one-half (1/2) of his days off (rounded up) as follows:
20-F-4-b-(1) For a full month absence, the Pilot must designate two (2) blocks of days off; 20-F-4-b-(2) For a partial month, the Pilot may designate only one (1) block of days off,
with a maximum length of five (5) days;
20-F-4-b-(3) When the proration results in only two (2) days off, the Pilot can elect to place a single day off. The Company may place the remaining day off at its discretion;
20-F-4-b-(4) After the Pilot designates his days off, the Company may rebuild the remaining schedule around those days;
20-F-4-b-(5) If the Pilot contacts the Company after 1300 on the day before the report time of a Trip or other duty already on his schedule, the Pilot may only move the Trip or first three (3) days of duty with Company concurrence.
20-F-4-b-(6) The Pilot is not eligible to place days off on a Holiday unless there is a Pilot junior to the affected Pilot (in Category) who was awarded the Holiday off.
20-F-4-b-(7) After the Pilot’s schedule rearrangement is complete, the Company may give the Pilot a set of new assignments, in accordance with Section 20-F-4-a.
20-F-4-c The provisions of Section 20-F-7 shall apply.

20-F-5 When the Company cancels or terminates recurrent training or a training assignment of less than five (5) days that was included in Monthly Schedule Preferencing, then duty days shall coincide with the originally scheduled training and travel days. On each day, Lineholders may be assigned a period of telephone availability of four hours in duration, Field Standby or flying. Such assignments shall be made when the Pilot is notified of the cancellation. Reserve pilots shall be given reserve day(s). The provisions of Section 20-F-7 shall apply.

20-F-6 Cancellation of training (including subsequent OE blocker days and any awarded flying of which the pilot is now not qualified for), when the cancellation was not initiated by the Company, or the cancellation of any other absence or activity (e.g., sick leave, military leave), that was included in Monthly Schedule Preferencing shall be handled as follows:
20-F-6-a The Company shall construct an initial schedule based on the prorated duty days. Lineholders may be assigned periods of telephone availability of four hours in duration, Field Standby or flying. Such assignments shall be made when the initial schedule is constructed. The period of telephone availability for training cancellation is for each duty day; otherwise the period of telephone availability is only on the first day of a period of duty days. Reserves shall be given a prorated number of reserve day(s).
20-F-6-b Within seventy-two (72) hours of construction, the Pilot may contact the Company and rearrange his schedule at his discretion. Rebuilt schedules must consist of three (3) to five (5) consecutive duty days (unless proration results in a lesser amount of duty days). If the Pilot contacts the Company after 1300 on the day before the report time of a Trip or other duty already on his schedule, the Pilot may only move the Trip or first three (3) days of duty with Company concurrence.
20-F-6-c After the Pilot’s schedule rearrangement is complete, the Company may give the Pilot a set of new assignments, in accordance with Section 20-F-6-a.
20-F-6-d The provisions of Section 20-F-7 shall apply.

20-F-7 The following provisions shall apply to Sections 20-F-4, 20-F-5 and 20-F-6:
20-F-7-a If the affected Lineholder picks up or is assigned Open Flying that fully covers a period of days owed, he shall have no further responsibility to the Company for that period. If he picks up or is assigned Open Flying that partially covers a period of days owed, with Company concurrence he shall have no further responsibility to the Company for that period.
20-F-7-b The telephone availability period, Field Standby or Trip report time shall begin no earlier than 1000 on the first (1st) day.
20-F-7-c The telephone availability period or Field Standby shall end no later than 1800 on the last day.
20-F-7-d The above procedures may be modified with mutual concurrence between the Pilot and the Company.
20-F-8 If a training assignment that was not included in Monthly Schedule Preferencing cancels or terminates earlier than planned, a Lineholder may be given replacement assignments, under the
provisions of Section 20-F-1, on those days on which he had underlying Trips published in his awarded schedule. A Reserve shall return to his original reserve schedule.

20-F-9 Treatment of Canceled Unpaid Absences Not Included in Monthly Schedule Preferencing
20-F-9-a When a Lineholder cancels an unpaid absence that was not included in Monthly Schedule Preferencing, the days underlying the unpaid absence will become days off and the Pilot’s pay will not be restored.
20-F-9-b When a Lineholder uses vacation to cover an unpaid absence that was not included in Monthly Schedule Preferencing, and if that unpaid absence is subsequently canceled, the vacation will be returned to the Pilot’s unused vacation balance and the Pilot shall become subject to Section 20-F-9-a above.
20-F-9-c When a Reserve cancels an unpaid absence that was not included in Monthly Schedule Preferencing, the reserve days underlying the unpaid absence shall be handled as follows:
20-F-9-c-(1) If the day on which he notifies the Company of the cancellation is an underlying reserve day, he shall be advised by the Company at the time of the call if he will sit reserve on that day. If so, he may be given a Short Call assignment beginning at or after the time of the call. If unused, such Short Call assignment shall not apply toward the MPG provisions of Section 3-C-1-b-(1).
20-F-9-c-(2) If the day after he notifies the Company of the cancellation is an underlying reserve day and it is 1200 or earlier on the current day, the Pilot shall sit reserve on that next day and on any subsequent underlying reserve days.
20-F-9-c-(3) If the day after he notifies the Company of the cancellation is an underlying reserve day and it is after 1200 on the current day, he shall be advised by the Company at the time of the call if he will sit reserve on that next day. He will sit reserve on any subsequent underlying reserve day(s) after the next day.
20-F-9-c-(4) The reserve’s MPG shall be restored by 4:03:20 for each day he sits reserve. 20-F-9-c-(5) The days underlying the unpaid absence that are not converted back to
reserve days shall be coded as RDO/HDO/FDO as appropriate.
20-F-9-d When a Reserve uses vacation to cover an unpaid absence that was not included in Monthly Schedule Preferencing, and if that unpaid absence is subsequently canceled, the vacation will be returned to the Pilot’s unused vacation balance and the Pilot shall become subject to Section 20-F-9-c above.

20-F-10 With concurrence of both the Company and the Pilot, alternate processes may be used, except as limited below:
20-F-10-a AV day modifications
20-F-10-a-(1) Requests to move AV days will not be granted until the completion of the
trip-trade run required by 20-P-3-c.
20-F-10-a-(2) Flight assignments must be contained within contiguous blocks of AV days. Replacement of an existing AV flight assignment(s) with a new flight assignment(s) must fill more remaining contiguous AV days. Requests to move unassigned AV days may be granted in order to comply with this restriction.
20-F-10-a-(2)-(a) Example: Pilot has three contiguous AV days and wants to be assigned a four-day trip, this is not allowed. If that same Pilot has a second set of three AV days (total of six), with company concurrence he can move one of the days to make one of the blocks four days in order to be assigned the four-day trip.
20-F-10-a-(3) Nothing in this Section 20-F-10-a shall prohibit the Company and the Pilot from mutually agreeing to drop any or all of the AV days without pay or remove any or all of the AV days with pay.
20-F-10-b If availability days are dropped without pay, the Pilot’s PTC will be reduced on a straight dollar pro-rate of the number of days dropped. For example, if a Pilot has availability days associated with an underlying four-day Trip that paid $3200, each day dropped without pay will reduce the Pilot’s PTC by $800.
20-F-10-c If availability days are dropped for vacation, the Pilot’s vacation balance will be reduced on a straight hour pro-rate of the number of hours dropped. For example, if a Pilot has availability days associated with a four-day Trip that paid 22 hours, each day dropped for vacation will reduce the Pilot’s vacation balance by 5.5 hours.

20-F-11 If a Pilot calls in sick on availability days, the Pilot’s sick leave bank will be debited on a straight hour pro-rate of the number of hours dropped. For example, if a Pilot has availability days associated with a four-day trip that paid 22 hours, each day dropped for sick leave will reduce the Pilot’s sick leave bank by 5.5 hours.

20-F-12 Whenever a Flying Flight Segment's airport pair changes prior to takeoff it shall be considered a loss of flying, with the Pilot subject to all reassignment rules, with the following exceptions:
20-F-12-a The destination airport is changed to one of the co-located airports listed in Section 5-E-1-h and the flight number does not change; or
20-F-12-b A planned fuel stop with no layover at the fuel stop city.
20-F-12-c Note: Unless subject to Section 20-M, a delayed Flight with no change in flight number is not a reassignment. A delayed Flight with a change in flight number may or may not be a reassignment depending on circumstances.

20-F-13 When a Pilot’s first activity in a Trip is deadheading, and if he loses his first Flying Flight Segment of that Trip, the following shall apply:
20-F-13-a If the loss of flying occurs after the actual Departure time of the deadhead, or if the loss of flying occurs before the actual Departure time of the deadhead but the Pilot departs on the deadhead, then Section 20-F-2 shall apply.
20-F-13-b In all other cases Section 20-F-1 shall apply.
