I am a huge believer in people quitting their manager, not their job.
A couple of months ago, I worked on a piece of work on my own. The product delivered was fully the product of my own work only.
Today, my manager sends a message to our group chat asking ‘Can someone send me ABC that TheGlossy & Golden Child worked on?’
‘Golden Child’ never worked on this piece - as a matter of fact, Golden Child was out on extended sick leave then. Yet the manager had the nerve to pretend they forgot it was my own work and tagged their bestie to it and gave them half the credit for something their never even looked at!
