Terrible company- do not work here - Customer Service Executive dusk Employee Review

I would highly discourage working here. I have been treated unfairly by managers in two instances. The first, I was 4 minutes late once due to bus strikes and then had a conversation with the new starters as I wanted them to feel welcomed - this was negatively commented on by management. However, when a colleague (also new to the company) was half an hour late to work, she was not reprimanded. The second, I was made to stay behind after a training session and told I reacted negatively to a comment made during training, and that I had a bad attitude. I spoke with the rest of the group in the training session who reacted the same as me and they said I did not appear to have a negative attitude. I feel the company is poorly run, with customers having to wait weeks for a response, and the office etiquette is questionable. There were instances of managers drinking alcohol during work hours, and people walking around barefoot. I would not recommend working here.
