I work at a small company of about 50 employees. Recently, our HR guy mentioned that there are a couple of very negative reviews on Glassdoor. The problem is that they look like I wrote them because they address the very specific problems I have with the company. My colleagues know about them as I have told them about it and they start to distance themselves from me as they think I wrote those reviews. I haven't written those comments but I am afraid that they will backfire at me as I'm currently looking for a new job. How should I deal with this situation? Just telling everyone that I haven't written them or be quiet?
they address the very specific problems I have with the company
THEY - multiple comments SPECIFIC - So an inside knowledge is presented I HAVE - and not only you. You need to realize, "If I didn't write them then it had to be someone else" ergo other people in company have same/similar problems.
So if asked and ONLY if asked directly say
I'm not the only one in this company with those problems. I just made a mistake of venting them out in company environment hoping something will change.
Do not deny the existence of the problem. Deny the authorship.
And most important - STOP caring about it. It's obvious that in your company the problem are resolved through ignoring them and shaming people who "bring out the trash".
As you didn't write them, unless you are asked by someone specifically the last thing you do is start a conversation about it and claim "it wasn't me" that instantly makes everyone think it was you.
Don't talk about them and don't mention them again.
As you are looking for a new job, I assume by 'backfire' you mean, you are worried people will believe it was you now that you are leaving.
Stop worrying what they think, it doesn't matter. Why do you think it does?
My colleagues know about them as I have told them about it and they start to distance themselves from me as they think I wrote those reviews.
Did they bring up the reviews with you or ask you about them? If not, I wouldn't jump to conclusions. You probably shouldn't bring up the reviews unless asked about them as it will only make you look more guilty. If someone does ask you about the reviews, you can certainly respond with something like:
I know I haven't exactly been quiet about my issues with the company but I don't feel the need to disseminate them publicly. I don't know who wrote the reviews but it doesn't seem like an appropriate way to vent frustrations.
If you don't have any direct evidence that the reviews are causing problems between you and your colleagues, it's very well possible that you're imagining a problem that doesn't really exist. You're better off just forgetting about it and moving on. Since you're planning to find a new job soon anyway, whatever perceived friction exists between you and your colleagues won't be a problem for much longer.
