My wife has been with her company for three years in a supervisory capacity with a staff of ten. She has had excellent reviews and meeting her KPIs at 98%. Recently the former supervisor realized that his position would soon be phased out and he and my wife's manager have collaborated together. As a result she was told yesterday that she does not think outside of the box enough and would be more suited to a position outside of her core competency with a substantial pay cut or she would be terminated should she refuse the offer. I felt that this seemed like a case of constructive dismissal and would like to know if she may have grounds to proceed and what steps should be taken.
