Don't be an apologist for bad management and bad people skills. If a boss or management ever called me and requested me to do a task on my own time, not company time, I'd politely refuse for obvious reasons. It's okay as a one time thing, "Hey David sorry to bother you at 7 but could you do me a huge favour and do X and Y? My bad I'll buy you lunch tomorrow" then yeah that's fine. But if it's spoken with any hint of authority or consequence they can fuck off.
