Complete lack of transparency. Frequently changes expectations wildly without coaching, explanation, or even notification. Inconsistent expectations between teams performing the same position. No pay raises unless you get a promotion. (Promotion differentials are minimal.) Behind the scenes changes of pay structures without notification until your check is lower.
For the last year I spent in this position, the entire team was incredibly overworked. There was far more expected of us than could reasonably be accomplished. We also could not take breaks without our workload being distributed to everyone else on the team, making their situation much worse.
