I’ve never actually had a colleague quit while I was there, buuuut, I did have a colleague disappear, here is that story:

I get hired by this colleague, seems like a nice, perfectly reasonable guy.

I’m supposed to be mentored in the codebase by him after I start.

Literally the day or day after I start, he gets a tap on the shoulder from someone in HR while he’s on the phone. He says he can’t come because he’s on the phone.

The HR woman insists, tells him to leave *everything* and he never returns.

Turns out the police were downstairs to arrest him.

He got caught up in Operation Yewtree which for those that don’t know, was the UK’s sting op on historic pedophilia cases.

MFW my manager gets arrested and the senior dev is too busy to mentor me, so I basically have to sink or swim 🤣
