I recently received my second write-up in just 28 days at my job as an assistant to the lead manager at a newly opened location. The first write-up, which I later found out was actually a Performance Improvement Plan (PIP), happened on May 13th, and the second one came on June 11th. There was no prior warning or discussion before either write-up. It's been a confusing and frustrating experience, especially since my boss went from being supportive to berating me in front of customers without any clear reason. I've been working hard, often going above and beyond, like actively seeking out positive Google reviews and even pulling weeds in the heat to improve our location's appearance. Despite my efforts, I receive no praise and only corrections for minor issues. My boss has criticized me for things like my shirt being untucked, which seems excessive. The latest write-up was for 'time theft' because I had to use the bathroom shortly after clocking in from lunch. My boss confronted me outside the bathroom, claiming I was being unfair to my coworkers for taking time to deal with a personal issue. I explained that I wasn't feeling well due to the heat and lack of sleep, but he insisted on writing me up anyway. I'm at a loss for what to do next. I feel like I'm being treated unfairly and don't understand why my boss's attitude has changed so drastically. I'm considering looking for a new job, but I'm also unsure about how to handle the situation with HR or if I should seek legal advice.
