AIO I Got fired over a disrespectful message

[u/BogusDuck]

For context, I’m the assistant manager (manager of the staff) and the front desk person at a Children’s Museum. Over the weekend, i discovered the fish tank unplugged at my work. The fish was dying and I tried everything i could to save him but had no luck (My boss didn’t let me leave to get anything that could help). I believe all animals should be respected as if they are a fellow human so I didn’t take this lightly and grieved for this fish. I texted my boss the next day giving my opinion about keeping fish here when no one has the training or knowledge (even if she does, she isn’t here all the time nor is willing to come in for such emergencies). She also leaves for trips so it’s helpful for someone else to have knowledge (like myself). I know i was a bit emotionally charged in my messages, but was this enough to be fired over? I’ve had no issues in the past and no serious writeups. I’ve done really well at my job and have consistently gone above and beyond what is asked of me, enough to be promoted to staff manager after 6 months of working there. I can see how what i said is disrespectful but in my opinion this could have been a write-up, not an immediate termination. Aio?

They started the post with Also.

So they sent something else before that. OP left some messages out

Full screen shots would be helpful.

I just read that as they were talking about something unrelated to the fish, but related to work; and then OP brought it up and then when posting, cropped out the part that doesn’t pertain to the issue they’re asking about

Yeah this seems like OP just went on a rant, I get it, they care about the fish. But they REALLY need to learn to not push boundaries with their boss
