Hi all. Messed up royally at work yesterday, found out today. Can't say too much as it's quite a niche role so potentially outing, but needless to say it can be fixed but will likely cost the company money, and also impacts another company who apparently are not happy.

I am relatively new to this job (been here since June) and it's a very complicated job with a high level of responsibility. I am just so annoyed and upset with myself. I'd convinced myself I was going to be sacked. I broke down and cried in front of my manager (so embarrassing and not professional I know!) and he was great about it, reassured me it's absolutely fine and not to worry. But I cannot stop ruminating about it.

What're the biggest mistakes you've made at work? Please say I'm not the only one who's messed up royally 😅

I was on a whats app work group
One of the members said something completely stupid.i proceeded to let off steam over this to my friend but voice noted it to the group. Noticed straight away within about 1- 2 mins. Felt terrible/ mortified / etc etc but you know its 4 months ago. No one said anything. The likelihood of lots hearing it is small. I didn't wait long enough to hear it as I was so quick to delete so whatever was recorded and sent might have actually been nothing / not !!. But I actually considered leaving over it. I'm told I'm a great worker liked by all but I was and still am mortified and ashamed of myself. #beatthat!!!

Op

how much money did your error cost

So to put things in perspective, I’m a mental health nurse, I’ve very sadly supported a number of patients who have gone on to end their lives.

I’ve worked with staff whose careers have basically ended because of the trauma of a decision they made meaning someone could find a way to end their lives. It’s awful because no nurse ever wants it to happen but it does.

I did cpr on a patient who sadly didn’t survive. It was years ago and it still saddens me now.

Most decisions don’t have any long lasting or really serious implications but for Doctors and Nurses, it really can be devastating for everyone involved.

Emailed the wrong set of parents about a child because two children had identical first names and surnames. Confidential SEN information was included.

I used to be a holiday rep and we’d hand out flight departure cards written by hand.

I put the wrong coach pick up time on someone’s card and they missed their flight home 😭😭 they didn’t question the time being so wrong either.

Oh god I've screwed up loads

Managed to insinuate in an interview I was gay, even though I was married to a man etc etc

That kind of shit

I paid the wrong supplier £3k years ago. Luckily they returned it but I was sweating for a while, it was a small company with bad cashflow.

I make/have made plenty of mistakes at work, most things can be fixed and yes they may cost money or take time to fix, but it also then helps make processes more robust and better to stop errors from happening again. Stop beating yourself up, especially if your boss has said it’s ok. I know this is easier said than done. The fact you care will mean a lot to your manager.

I don't set a foot wrong.

However, how long have you got for my personal life? Grin

I worked in a pub where the shift lead before me hadn't connected the lines properly and let loose the entire stock across the cellar floor. That was a bad day for everyone, the landlords rage, oh boy.

Oh bless you! If your boss has said it’s fine and not to worry then believe them.

I know someone who thought it was an inset day yesterday so didn’t turn up for school. An adult member of staff, not a child. This person is genuinely amazing at her job and is great to work with, but everyone makes mistakes.

Sent an email to a client that was meant for my manager. Luckily it wasn't against the client just a rant
