So, I've mentioned that I work weekends before and that I do 10 hour shifts. Which is okay! I quite like my schedule, because I get 3 days off a week.
Anyway, if the IT department is doing heavy maintenance, they will take the whole system offline. Out of necessity, they will do this Sunday morning. So while we normally start at 8 or 10 on Sunday, we're not allowed to come in until noon when there's going to be a system outage. We also have to do make-up time for the lost hours Sunday, which means coming in on a day off or shuffling hours around to other days.
The ridiculous thing is that we've had unscheduled scheduled system outages for all but five weekends so far this year. And while they sometimes give people two or three days notice, sometimes they send out the notification on Friday - at like 4pm. I mean, I default to assuming it'll happen now.
Having no life and living close to work, the constant wild last-minute schedule changes don't affect me much. And I just tack the extra time on the preceding Saturday and do a 12-hour shift, which is also not really a huge deal for me. But I can't imagine it doesn't drive everybody else insane. If this is happening literally every Sunday for months on end, can you not just schedule it officially instead of playing up at being idiots?
