The whole place is terrible. I used to go to bed and dream about being employed in a Victorian workhouse. I would wake up feeling refreshed and excited about my day ahead, eating gruel, pushing rocks endlessly up mountains and being flogged by a wretched man wearing a dirty leather apron and a surly grin. Then I realised I had to go into the Bristol office and my day instantly hit the skids.
On a serious note, it is a HORRIBLE place to work. The culture is one of backstabbing and grief. The management are stuck in the dark ages. There is no HR, so if you have any issues you have absolutely nowhere to go.
Also - check your contract - anywhere that gives you a one week notice period post probation is clearly looking for an easy way to dump employees. And GDS love dumping employees.
