I’m going to keep this vague so as to not out myself.
I work in a team with multiple subdivisions. I am the most junior member of the team and so I help across all subdivisions.
A few weeks ago during the really hot weather we were severely understaffed. I was working across six subdivisions alone.
I made a mistake. It wasn’t catastrophic, nobody died, no money was lost. I told a client the wrong information and they missed an appointment. It has been rectified, the person the appointment was with was very unhappy but they have moved on.
All management at the time (bar this manager who was not here) said it was fine. Accidents and mistakes happen and it’s not going to end in anything serious. That sort of thing.
Today one of my managers asked me to help on the subdivision that the mistake happened in a few weeks ago. They made a comment - “make sure you do it properly this time” (but referenced the actual mistake I’d made. Basically a snarky “don’t do that again”).
AIBU to think that’s totally uncalled for? I held my hands up, admitted my mistake and made it right. To make a snarky comment three weeks on just feels really out of line.
