I am stuck in the SCETA Dual Education Program - SCETA Dual Education Program Siemens Employee Review

I have an engineering degree but I was assigned a role in an unrelated field. I completed my sceta co-ops in this unrelated role and when I asked at the end of the program if I could switch to an engineering role I was told “no.”. The sceta contract that I signed as a student locked me in for four years with siemens. I have to stay with the company or I will be fined $40,000. I feel a lot of resentment towards the company and the position. I wish that I never joined in the first place.
