Before I started working for you, I idolised you. Your office looked incredible and I couldn’t think of anything better than having dogs running around my feet as I worked, and in-office play equipment which took me back to the days I spent running around soft play areas as a child. I couldn’t have been more infatuated, until you started talking about mental health. When you told the camera how supportive your company was, I knew I needed to work for you.

It wasn’t long before I realised the attention you had gained was exactly what you wanted. Unfortunately, the side your adoring fans don’t see, is the side of the dictator who most of your staff are scared of. Once you made the redundancies right before the Christmas break. The people you thought admired you were too afraid to talk about their issues with you around. This is probably why you weren’t aware of my mental illness until my line manager spoke to you.

Within an hour of my line manager speaking to you about my breakdown that morning, you decided to let me go. This was probably because it says in my contract to you that said that you have the right to let anyone go who becomes a mental health patient in any capacity, even if they are just being assessed. Which is an illegal policy, but it’s never been challenged.

I still can’t believe you tried to call me slanderous for coming to the conclusion that I was let go as a result of my mental health. If I was really so unreliable, why was all my work completed on time? And if there were so many mistakes in my work, why was I not given the chance to rectify these, and why was I only told when I had lost my job and there was nothing I could do?

I was still learning, mistakes happen and nobody can progress if they are not told they are doing something wrong. I’m honestly still trying to understand why I hadn’t been spoken to before about this. I think I will always remember the moment I walked into your office; being told I was allowed a witness before swiftly having the door shut behind me. You knew you had something to be ashamed of, which is why you didn’t look shocked when I told you I would be seeking legal advice.

Unfortunately, your staff are still too afraid to speak out. Either that, or they just can’t see that you’re doing wrong. I wonder how long it will take you to see that allowing another puppy in the office, or agreeing to catering from local suppliers isn’t the same as providing a stable support system for your staff, as I know there are still members of staff working for you who struggle just as much as I did, if not more. I truly hope you didn’t mean it when you told me the mental health clause in your contract was standard. If you honestly believe that it is okay to judge someone on their health when they can complete their job to a high standard, then do you not deserve to manage such a large number of people.

I was willing to try to rebuild after my traumatic experience until you made public statements about mental health. What disgusted me the most was that you looked so sincere about your beliefs on the topic. Watching you spew how you care about the struggle people face with depression and anxiety ironically made me more anxious. Reading the comments just made it worse. It was awful to see how people believe you genuinely care, but they aren’t to know any different. Your personal brand team keep your PR tight, I’ll give them that.

I sincerely hope you have learnt your lesson since the messy situation we encountered, purely so nobody else endures what I did. Please listen to your staff, let them speak and learn from your almighty mistakes.
