I’d imagine there will have to be some clarifying language from the union at some point since this section is about as clear as mud.

The TA references “legal rest starting at 0000” in the example given for an 11am show. My guess would be that you’re not required to answer your phone, but will still be required to check your schedule at some point prior to 2359. As long as the event was placed on your schedule at least 18 hours prior to show time, it is legal. If you choose not to receive text notifications for schedule modifications or not check your schedule until 2359 the night before, that’s on you.

In either case, being required to answer your phone or not, I’d say it’s a step backwards in LDO provisions for reserve.
