Can I post an exposé about my current job?

Hey guys,

I plan to leave this job on Feb 1, 2025 and have already handed in my notice.

I would like to write an exposé and share it to the city’s subreddit, but I’m not sure if there are legal repercussions for taking this action. I don’t want to get in trouble. At the same time, I want people to know how bad of a work place this was and what kind of owner they are supporting.
