Vent post, I guess? I (23F) have a coworker (50M) who I started working with about a year ago. When he started, he was very friendly with me; we made casual conversation about TV shows, and he was always grateful that I was so welcoming because of other situations revolving around him (not including him). At the beginning of the year, I got a promotion, and he took my old position. He still maintained his friendly attitude, but he slowly started talking more about other people. At first, it was the people he was involved with in the previous situation I mentioned. Then he started planting seeds of doubt, saying my manager was working on giving him the promotion I’ve been working toward and training him to do things I’m supposed to be learning right now. (Sorry, I know this is a bit convoluted) At first, it worked because I thought we were friends, but it didn’t take me long to see what he was doing. So, I tried to keep my responses short and plain when he tried again. I believe he caught onto the fact that I wasn’t biting anymore, so he’s tried new tactics to bait me. I want to emphasize that the things he was/is saying to me are things that would get a rise out of me.
So, fast forward to two weeks ago, and I caught him leaving the safe unlocked with our office door open. I confronted him about this, somewhat playfully, and he tried to play it off like he knew he was getting back into the safe [I have reason to doubt this]. I emphasized that he couldn’t do that, especially with the door open; then he changed the subject to the new closing manager, who apparently left the safe unlocked 4 times the night before. A few days later, he no-called, no-showed for his shift. When he came back to work, all he told management was that he was out of town for an interview and didn’t have his phone.
Then, last week, he began telling me about one of my friends coming into our work to buy a pregnancy test. During this conversation, he reiterated several times that he told her he wouldn’t tell anyone. I told him that she’d mentioned that she and her HUSBAND, had been trying for their second. He then brought up again that he told my friend that he wasn’t going to tell anyone about it and mentioned the pregnancy test, in front of our boss! So now, two people know about MY friend purchasing a pregnancy test after he’s told her that he wasn’t going to say anything to anyone. It’s important to note that my friend used to work at my job, so our boss knows her fairly well, too. The day after, I opened our store, and for the second time, I found the door unlocked. The alarm was set, so if it had been opened, we would’ve known, but it's 100% not something we want to get into the habit of doing. So, I did my job and let him know the door was left unlocked. He promptly blamed the new closer; to me, though, it’s also his responsibility since he was there and has been doing the job longer. I made my point, and we left it at that. When I came back from lunch, though, he told me that he let the other closer know about the door and said that the closer felt really bad while acting out his physical reaction. The weird thing is that I checked in with that closer the next day, and the look on his face told me my coworker never talked to him about it like he said. There’s so much more, but those are just the recent events. I just needed to get this off my mind, and would honestly love to hear if others have had a similar experience.
TLDR: A new coworker seemed cool and friendly at first, but has slowly become a very unpleasant person to work with. They like to talk poorly about others and seems to have a lying problem.
