I recently accepted a job offer after four years at my previous company, where I was quite happy. I went through three rounds of interviews over five weeks and received an offer letter that was significantly better, about $25k more than my previous salary. After signing the offer, I put in my two weeks' notice and my old company was supportive, even throwing me a little goodbye lunch. However, just three days before my start date, I received an email from the new company's HR department stating that the position had been eliminated due to restructuring, and they were rescinding the offer. This left me in a tough spot, as I had already quit my job and now found myself unemployed with rent due in just three weeks. I immediately reached out to my old manager to see if there was any chance I could return, but he mentioned that they had already begun the process to backfill my role and would need approval from his director. There are no guarantees, and I feel completely at a loss. I'm also wondering if there are any legal options available to me since I relied on their written promise of employment to my detriment. It feels incredibly unfair, and I'm left feeling angry and anxious about my financial situation.
