My question involves labor and employment law for the state of: California and Wisconsin
My company informed its work force last year that the site I work for in Wisconsin would be absorbed by a site in Los Angeles, CA. I was given an option between transferring my position to Los Angeles at a salaried rate (increase in pay and switched from hourly to salary). The offer included a cost of living increase, relocation, and I negotiated that they allow me to fly back to Wisconsin to complete the last semester of an academic program.
By signing the employment agreement, I was told I would be ineligible for severance. I have now been told there was a mistake in the letter I signed - and that I am going to continue to be compensated hourly rather than salaried. Additionally, I have been informed that they will have to revisit whether they will allow me to have a flexible work schedule while I finish my education. When I informed HR about my hesitance to schedule relocation activities after hearing this, I was reminded that I am ineligible for severance.
Do I have a legal leg to stand on in getting my severance given that they changed the written offer that I signed?
