Shortly after starting a new job as a retail assistant I was promoted to supervisor. I had to complete online training and read the contracts, it was all quite official, and other members of the team were told. A few weeks after this I was told someone else is up for consideration but that I need to compete with this person to get the job.
a few weeks after this I see on the scheduling app that the other person got the supervisor role. My boss hasn’t even had the decency to tell me I didn’t get it. She also didn’t give me a fair chance, only teaching the other person the supervisor duties. Am I being unreasonable that this is unfair and how do I go about this.
