Unclear responsibilities
Poor management
Poor training
High turnover
Expected to be at every other department's beck and call
Constantly changing schedule
Poor career opportunities and raises
Low pay for the amount of work you undertake
Doing good work means you undertake more responsibility for no benefit
Doing poor work nets you a sternly worded email and possibly a meeting, but no other 'real' consequences. It’s possible to stay here doing sub-par work and causing issues for years while others pick up your slack.
