I work in a warehouse with about a dozen other guys.

Pretty much nobody likes the manager, and three guys have quit so far saying it was because they couldn't work for him.

One of my colleagues is now being very open about how pissed off he is about how the warehouse is being run, and he frequently displays his contempt (for example drawing doodles during a meeting in the office).

The lady in the office made up a letter to give to the health and safety officer to pass to my colleague. She wants my colleague to see his doctor and to have his doctor say whether he's "mentally stable".

This has really caused havoc among all my colleagues.

My colleague who received the letter has been walking into the office with his smartphone recording video and audio, and he has recordings where he asks for the form about "mental stability".

I don't know how far this will go... but some people think it's a really big deal, as in it might make national news here in the UK.
