Pay scale compared to other companies could be better. If I were willing to move, I know I can a much better paying job. But, since I'm not, I'm stuck with what they will give me. I've been employed X yrs, and a new employee of only a few months is being payed almost the same as me.
Random schedule; if you want to call it a schedule at all. Can't really make plans outside of work because of last second instances, which leads to staying late for work or extra work the next day, leaving me to sometimes scramble and find someone else to get my kids from daycare. The only way to have a true day off without the chance of being bothered is to use vacation days.
