Hello community,

This is my first post, seeking your advice.

I have been assigned on new specific job for six months since I were the only employee meets the job required grade code ( two years so far). However, when one of my colleagues received a promotion last week, my supervisor, who is from the same region and denomination, intended to assign him as senior operator instead of me. We deal with new security system, so nothing beyond my capability and pre-experience for my colleague as a communication dispatcher is not reasonable justification. By this discrimination, my chance to get promotion in the near future will be impossible since there is only one job slot for a senior operator. I feel disappointment and want to raise this complaint to the department manager in official way, Can you help ?
