As as the title says, I got paid this month by mistake while I am in paternal leave. First I thought I got an extra annual bonus or something and I didn't had time to call my employer to ask what was with it. Few days after that I got a call from the HR and they asked if I could transfer the money back because it was a mistake. I didn't want to get in trouble or something like that so I just sent their money back. Only after that it crossed my mind that I had to pay a transfer fee for their mistake and I don't think it is fair to be honest.
What would you do if you were in my place?
Sorry for grammar mistakes, English is not my first language.
