If you were an hourly employee and someone from corporate office reached out to you outside of work hours, what would you do?

I'm tempted to message back and say something around please either pay me for OT if I'm considered on call or just ignore it. I hate my company (they've been sued three times in a 2 year span and lost all 3 cases) for devious shit. In addition, this woman is the Bane of my existence and she's one of the least liked people in the entire company. I'm planning on leaving anyways but its also only the first time they've reached out outside of office hours.
