I was laid off of my job 2 weeks ago due to budget cuts or that is what I was told. I was given a letter agreement to sign saying that I would receive 2 weeks of severance pay & if I signed the letter I would receive an additional 2 weeks

Severance package letter was signed & I sent it certified. I have already filed for unemployment. They laid me off 2 days before I was going to take my PTO which I had 10 days but do not get paid for that when you are terminated. They said my job was eliminated due to budget cuts but offered me the same job 2 weeks later. I do not trust them & feel like if I went back to work for them I could be terminated again. I have already registered & paid $1250 to go to school to get certified in medical coding & the hours that they want me to work would not allow me to take this class.
