I was hired by a company to develop a product a year ago, I have worked on this product exclusively during the last year and the intention was to move up to a managerial role with two more people as subordinates.
Last year, the company had also acquired another company whose product competes with mine. I learned this while on the job.
I have indirectly learned that the decision has already been made that I would need to throw away all that I have done during the last year and my job would become following instructions from the people at the other company, developing their product. Their product is objectively precarious from a technical point of view.
I was planning to explain my vision for the department this week, but I feel it will be for nothing. Ultimately it is just me competing against a company, and the company also gets more support from senior management, such as investment, new hires and so on. Also, the decision has already been made.
How should I react to this? I was planning to request a change to another department which I feel would value my skills more.
