Went back into work today after the weekend. I noticed the Parts Manager got pulled aside by the Ops Manager, but didn't think much of it. Got pulled aside myself 20 minutes later and was fired by my PM, who wasn't particularly happy to tell me the news.

The order supposedly came from top brass who said they "had a bad interaction" with me I still can't single out, and that I was on my phone too much. I use my phone to take pictures of shipping tags to receive, and I am the only person in the department with a camera mounted directly behind them. Yippie.

All this just after receiving a Christmas bonus and a gift card from my Parts Manager, so this was completely out of left field. Was almost six months into the job and was told I was "progressing very well." Not really sure what do do now, I just need to get it off my chest.

Edit: I am definitely not perfect. I have no doubt in my mind that I slacked at points. In the last month, though, I made an effort to improve the quality of my work and the department. I heard no further complaints, was rewarded for my effort, and my Parts Manager was not involved in the decision to let me go.
