I have changed a few details to avoid anyone knowing my identity and my managers on here.
Ok so my manager was the nicest manager you would meet very friendly and approachable always happy with your progress no matter how small and today they just up and quit sad but everyone knew the top bosses were pressuring my boss to perform to a higher standard on barely enough staff. She was constantly berated by managers for not completing specific tasks and despite that they always came to work on time always came with a large smile on their face and made everyone else's day a good day.
Now they quit and we're all waiting on the shitstorm that is management to blame us, yay teamwork.
