Lack of training.
Lack of feedback.
Other companies pay better.
High turnover rate.
Lack of handover.
Understaffed and overworked, too many events and too little people.
Expected to work during the weekends/when on annual leave. Some evening/weekend work is unavoidable on site, but not over Christmas break when the office is supposed to be closed.
Toxic atmosphere, managers don't tend to lead by example, telling you how to do things/speak to people/handle situations and do the complete opposite.
A heavy drinking culture, often looking down at people who don't drink.
Lack of empathy and support for struggling employees, if you don't fit in then you'll probably struggle here.
