You really haven’t read your PWA.

“A short call pilot must be promptly available for contact“

“A regular pilot who is removed from a rotation due to IROPS [ … ] and they are notified of such removal after they have reported for their original rotation will be immediately available for contact“

“A VAS period is a period of availability in which a pilot will remain on the airport premises for a period of up to six hours (the standby window), during which they may be required to depart immediately on flying assigned”

but okay, keep up the good work shaming pilots who aren’t dropping everything to get to work in 15 minutes or actually exercising their PWA right.
