The managers had no idea how to do their jobs. You can't trust a group of people in their early twenties, with no experience, to run a club charging £300+ a month.
You had to side with the managers, even when the choices were clearly wrong. If this was a ship and you were about to collide with an iceberg, you'd want to steer the ship away. But if the managers wanted to keep going forwards, and you wanted career progression, you had to side with them or be blacklisted for not being a "team player".
The management culture ruined the experience even more. The managers would only hire "their type", rendering the company's own hiring policy completely useless. There were times where people were hired with no interviews or trial days. People would get rejected for positions they were more than qualified for but were looked over in favour of who the managers saw as yes men.
There was a time a woman became a supervisor and at this time her attendance at the job was about 50/50 as an assistant, but as a supervisor, we were lucky to see her twice a week if that. Shifts were five days on, minimum. This was allowed to continue for half a year with no action taken by management to address the issue. It took a completely new manager to come to our department and let her go.
