Some management and senior staff are bullies and treat you badly knowing how it's affecting people. Absolutely one of the worse places I've worked due to being bullied and them twisting things around. They knock your confidence and expect you to know everything within a day of starting and if you don't they will make you feel useless. They don't care about their staffs physical and mental health, they just want you in working.
HR are also so rude and unhelpful and clearly on the companies side. I even got the phone hung up on me by them.
