I have proof that he has been hacking into my version control branch and changing my code so it looks like I can’t complete my assigned tasks and then telling higher ups that I don’t know what I’m doing so he can get me fired. This came about because he kept coming to me saying my code doesn’t work when merged to master branch and I told him that can’t be because I already tested it and it worked and then I went back into my code and it got changed dramatically, so I decided to backup my code by sending it to myself to my phone on a notepad whenever I got it running and then magically the next day the code was completely different and my manager would magically call me into his office to discuss my “bad code”. How is this even fair? Should I submit proof to higher ups that he is trying to sabotage me?
