I can stay late any day except Monday if I have advance notice--and I can stay late on Monday if the advance notice is more than one day. I have to pick up a child from daycare and they close at 5:45. If I have to get someone else to pick him up, I really need to know that morning so I can find someone.

I have offered before to pick him up and bring him back to work with me to do the late work...it hasn't happened often, but it has happened.

Most of my bosses have children too and don't expect me to be a robot on call 24/7.
