Cons
I worked in the UK&I Marketing department. When I joined I loved it, the atmosphere was great, the team was great. Then there was a change of leadership, and everything got a bit rubbish. No matter how hard you work, unless you are necessarily brown nosing then you will not get recognition. People who were down right thick seem to get all the exposure just because they were brown nosing. They demonstrated no actual successful work, were repeated getting other people to do their work and taking full credit for it and couldn't get to grips with the basic systems yet still managed to get promoted. It got to a point where I hated being there because of the amount of clear idiots in the department who just keep creating more work from all the mistakes they made, and the refusal of management to accept that the department was full of morons. One in particular who only got the job because of their connections, but who repeatedly is messing up the most basic of tasks such as sending emails to clients, putting the firm at risk of Data Protection regulations. Not to mention how they screw over returning mothers and those who will be going on maternity leave. After repeatedly asking for more challenging work, broadening my skills and unsuccessfully applying to an internal role, only to be told it had gone to someone external because I did not have digital experience (which we weren't allowed to get because there was a dedicated digital team), I had the last straw and got out of there. I found out after I had left that my senior manager had been blocking other managers and senior managers from using me when they needed help, and telling them that I was too busy. Even though I was bored out of my mind and asking for more things to do.
