I'm all about family time and vacations but to take a random night off without any plans is a wasted day for me.
SO if your terminal would call you and offer to give you a Friday night off just before you left for work, you wouldn't say yes? I would in a heartbeat. My home time is far more important to me than money and I will take any opportunity to stay home that I can. With that said, if I stay home at AE's request, I should be given an added attendance point (i.e. I have 14 in the bank, I should then have 15). I think that is fair.
