I'm on call for this week. That means phone calls at 3am from total strangers regarding things I can't control. But I'm lucky I only have to do it one week every 4 weeks.
Normally the way things work, is we get to specialize in our field and run our little projects. But 1 week out of every 4 we are the jack of all trades and the weight of all those users sit on your shoulders. Sure you can get people in the group to help you out. But for that one week you are riding the rocket and all of your regularly scheduled problems are put on hold.
Wish me luck, I didn't get much sleep last night. But I can't complain as those paychecks continue to cash.
