Boss told Co worker about my mental health issues.

Nothing except that the worker in question was on sick leave, would be my expectation.

Nothing, absolutely nothing.

Management : ”Onóir is out of the business going forward and when they are due return you will be notified”

Staff : “yeah but why, what happened come on”

Managment : “ a temporary leave of absence, is what’s happening, that is the end of the matter and we do not and will not be discussing private details relevant to another persons employment “

Madness that you'd expect them to assume that something so private would be revealed.

A real insight into how you'd handle such information I guess.

that would give the manager if they are guilty.. ‘wiggle room’ and time to plan a defence.., a heads up as they know what you know.

the vast majority of managers dislike HR as much if not more then frontline employees…

when they get the invite to the chat they are already behind the 8 ball. Don’t let them play safe.

FFS, that's terrible. A total breach of confidentiality. I'd lodge a formal complaint but I know it's easier said than done. Your manager is totally out of order.

@bucketybuck i feel sorry for people like you - really. - i do. soo.. ignorant.. to say the least..

i hope you resolve whatever issues are killing you

I'm not incorrect, because I never once said it was the managers job to spread rumors.

The Op was originally in a different forum, and my point from that perspective was that it is incredibly common that co-workers know why somebody is absent, through many different ways and means. Its not right but reality is what it is regardless.

So since that is the case, how should a person react? Do you be shocked that people knew, or do you act as if you expected it? That is the starting point of looking at the question from the perspective of the other forum, which is a very different context to that of a forum for obvious workplace breaches of conduct.

Would a job be comfortable with an employee going to whatever third party and telling them about issues in the workplace, say health and safety ? Financial or the likes ? They wouldn’t, you’d be disciplined could it be proven…you have a contract signed that will say you can’t do that.

likewise a company cannot impart information related to your health to your colleagues / fellow company employees, it’s illegal.

A company * might say “ hey you know, would you consider sharing just the general ‘gist’ with the team, but no, would mean no.

These situations often aren't so black and white.

But this case, when you have a team member telling you that they were informed of the details, by your manager, is as clear as it gets: The manager has clearly used the information for a very different purpose than it was provided for. It's a massive GDPR breach, of sensitive information.

But can you prove it? It's likely that the employee will lie thru their teeth if asked about it in an official investigation.

You really need to think hard about what you want to achieve. Especially given your history with this manager, you now have enough ammunition to take a very damning case against them. But without concrete proof, you may not win. Either way, it will be stressful.

Before going anywhere near HR, I'd look to talk this thru in detail with a mental health professional. Either your psychiatrist, or a therapist they recommend who is clued up about workplace issues as well as your diagnosis. Basically someone on your side, but impartial. (Remember: HR are NOT on your side, their job is to minimise the company's liability.)

Also - it does seem kind of odd that the other employee remembered so much detail. Even if the OPs manager was talking out of turn, people won't usually recall all the detail of what was said. So I'm wondering if the other employee came upon the letter, and is using it (and you, OP) to try and get the manager into trouble. Stranger things have happened in toxic workplaces, and this certainly sounds like one.
