after 14 years can I be transfer to smaller place

If you are represented by a union, the first person you should speak with is the union rep, or the Business Agent (BA) if the union rep does not give you a clear answer.  Typically, transfers and assignments are covered by union seniority, but only up to a point.  There is often some exception in the union contract allowing business reasons to control over seniority, but there must be a valid business reason.  The questions that you or your union rep should ask of the company is why you are being transferred and why you are being replaced by a new worker.  If the reason sound suspect, there may be a possibility that age discrimination is a factor if you are over 40 years old
