I'll post from the two sections I found from CA 09-12, and namely the TWG. Those TWG's are not only critical reading for FMNWADALNNORTHIESPMNW pilots, but for the FMDALDALSHICKSREBELSGOODOLEBOYS pilots as well. If you came in 2007 or after and still scratching your head about the contract, the TWGs are great. The JCBA establ;ished the TWA to "facilitate the education and integration of former NWA pilots into Delta scheduling and PBS systems and rules."

source: Know Your Contract, Section 23

The Company may remove a pilot from a rotation or portion thereof and he may be eligible for a guarantee under other provisions of the PWA (e.g., Section 4 E., F., H. etc.). A reserve pilot who is removed from a rotation(s) will not be eligible for a rotation guarantee under Section 4 F., and will remain on-call as scheduled.

Depending upon the circumstances of the removal, the pilot may be subject to reroute or assigned recovery flying. (See also: Sections 23 K. and L. and TWG Notepad 09-13)

Regular First Officers Removed for OE
If a regular First Officer is removed from his entire rotation for another pilot’s OE, he will be subject to recovery flying under Section 23 G.5.a.

1. The Company must attempt to notify him of his recovery flying at least 12 hours prior to his original report. If he has not been assigned recovery flying by that time, he has no further recovery obligation.

2. He can be assigned a single rotation that reports on any day of the original rotation but
NET his original report, and releases NLT four hours after his original release or the
same calendar day, whichever is later.

a. If the assignment to recovery flying is being made within 24 hours of his original report and the recovery flying reports on the same day as the originally scheduled rotation, he will only be assigned recovery flying under Section 23 N.3. (after white slips).
b. If the assignment to recovery flying is being made more than 24 hours prior to his original report, or the recovery flying reports after A day of the original rotation, he will be assigned recovery flying prior to any assignment made under Section 23 N.1.

3. If he is removed from all or part of his recovery rotation, he cannot be assigned additional recovery flying.

4. If he has not acknowledged his recovery flying three hours prior to his original report, the recovery flying may be removed, and he will be subject to recovery flying under Section 23 K.1.
(Refer to “Regular Pilots Removed for IROPS” above). In this case the pilot is required to be promptly available at his base at the originally scheduled report time. He may be assigned recovery flying scheduled to release NLT four hours after his original release or the same calendar day, whichever is later (domestic). An international category pilot may be assigned recovery flying scheduled to release NLT 30 hours after his original release, provided the last duty period of the recovery flying contains an ocean crossing.

Example 1:
A First Officer is scheduled for a rotation reporting on Wednesday at 1600 and releasing on Friday at 1700. The Company removes him from the rotation for another pilot’s OE, and he acknowledges his assigned recovery flying no later than 1300 on Wednesday.
Results: 1. The Company may assign him a single recovery rotation no later than 0400 on Wednesday.
2. Recovery flying may report no earlier than 1600 on Wednesday and must be scheduled to release no later than 2359 on Friday.
3. After 1600 on Tuesday, the Company may assign him recovery flying reporting on Wednesday only under Section 23 N.3. (after white slips).
4. The Company may assign him to recovery flying reporting on Thursday or Friday prior to any assignment made under Section 23 N.1.
5. If no recovery flying is assigned by 0400 on Wednesday, he has no further recovery obligation.

Example 2:

A First Officer is scheduled for a rotation reporting on Wednesday at 2100 and releasing on Friday at 2100. The Company removes him from the rotation for another pilot’s OE, and attempts to notify him of his assignment to recovery flying prior to 0900 on Wednesday. The pilot does not acknowledge the assigned recovery flying prior to 1800 on Wednesday.

Results:
1. The pilot is subject to recovery flying under Section 23 K.
2. If he has acknowledged his removal from his original rotation, he must be promptly available for contact by Crew Scheduling from 2100 on Wednesday until the earlier of:
a. 0300 on Thursday,

b. His assignment to recovery flying, or
c. His release by Crew Scheduling from recovery obligations.
3. If he has not acknowledged his removal from his original rotation, he must report at his originally scheduled report and be immediately available for contact by Crew Scheduling until the earlier of:
a. 0300 on Thursday,
b. his assignment to recovery flying, or
c. his release by Crew Scheduling from recovery obligations.
4. His recovery flying may be scheduled to release no later than 0100 on Saturday (0300 on Sunday if the last duty period of the recovery flying is a transoceanic duty period).
