Stale CEOs need those youthful and educated employees to help them to feel good about themselves.
I felt like a newbie even when newer starters joined. Once the department had doubled in size it became clear that the only future for me was to work like a donkey so that the chosen ones would not have to and to train said chosen ones to replace me. As the department grew the environment became increasingly unpleasant, 'competitive'. Required to make up time taken off even when signed off with a GP sick/fit note but still penalised for taking time off by cold management, 'if you can't do the work we can get others to do it'.
You will be asked for your ideas and suggestions but unless you fit in you will not be credited for those ideas and suggestions worth merit. Instead this is like a way to harvest as much value from each employee as possible before kicking them to the kerb.
Hard work will not help you to get on if you do not 'fit in'.
If you don't fit in you will find that there won't be room for you at the company parties.
My mental and physical health have suffered as a result of working with this company, in some ways it has been the best but in more and worse ways it has been the worst.
