I've been working at a lab for nearly three years, and things have taken a turn for the worse. After we lost a major client, the company laid off about 30 people, leaving my department with just me. Normally, we would have three people, but now I'm handling all the work alone. This year, my raise was only 1%, a significant drop from the usual 3.5%. I suspect this is because I had to take a week off last year when my son was sick with Hand, Foot, and Mouth Disease. When I approached HR about options for leave or FMLA, the rep was dismissive, suggesting that a sick child wasn't a valid reason for missing work and implying I should have found a babysitter instead. In early April, I reached out to my manager for a raise, providing evidence of my contributions, as I was doing over 50% of the work in a three-person team. Unfortunately, my manager is known for not responding to emails, and after a month of silence, both of my colleagues left the company. In total, four people have quit recently due to the poor work environment. I finally scheduled a meeting with my GM to discuss my workload and the lack of a proper raise. She promised to talk to HR about it, but that was two weeks ago, and I still haven't heard back. I even sent a follow-up email to check on the status, but no response. With the situation deteriorating and no backup for my position, I'm considering whether to put in my two weeks' notice or threaten to quit to prompt some action. My manager is pretty hands-off, mostly sitting in his office on his phone. It's frustrating to see others being begged to stay while I feel completely undervalued.
