My company has had several rounds of layoffs and yet I am still around. All the most pleasant, helpful people were let go while the loudest jerks who shirk all the burdensome tasks remain. My job satisfaction has degraded significantly and I'm being assigned responsibilities that are very unappealing. The nature of my job has really changed since I was hired and I think it's only fair that I should be let go with the standard severance package rather than have to quit on my own accord. Am I within my rights to refuse the change in responsibilities and demand proper severance?
