I have always felt that according to the ALPA 117 guide Q/A 36, I need to be put on rest before they can assign something to me. According to Q/A 37 I can volunteer to pick up.

Q-36. A flightcrew member is on days off. Can the company call him for a flight assignment?
A-36. Yes. If the flightcrew member answers the call, the company can assign him to flight duty. However, the company must give the flightcrew member the required 10- hour rest period and then place him on short-call reserve.

Q-37. Can a flightcrew member who is on days off voluntarily elect to pick up a trip from open time?
A-37. Yes. This is not prohibited by the regulation so long as the flightcrew member is rested, fit for duty, within applicable limits for duty and flight time, and prepared to perform the assigned duties.

If that doesn’t work:” sorry, drinking beer, thought is was for an X list for tomorrow.” (I list for the whole month for both X and Y (currently not for Y) before the first, and have since XY started. Never had anyone tell me I could only list for the days I was actually available.)
