My boss did a good job of standing up for/advocating for his employees and trusted us (especially those of us who were returning employees) to know our own limits and what we could and could not handle. He made sure to keep up-to-date with out training, issues, and do extra training days or one-on-one meetings to ensure we were on the same page and functioning at max efficiency.
What I wish was different
Had some issues with upper management that made the work environment frustrating and sometimes downright hostile. It was manageable and ignorable, but due to understaffing, a bit obnoxious to deal with constantly.
Advice
It's a great job for gaining skills, both professional training and personal/interpersonal.
