I'm an R&D engineer, my job description explicitly states that and states that I am involved in the entire development process. Now they are trying to get me to act as a QA engineer and an installation engineer and the post-development process. It's only temporary, but I'm not qualified or willing to do either job. I told them that they needed to move me back to my job as outlined in my written description, or renegotiate my contract, where I would demand additional compensation. Is there anything else I can do to make sure that my employer respects the job description that I was hired for? I'm more than qualified to find another job, but other than the past month, I like where I am.
