My employer makes us request all our vacation before November of the following year. Requests are granted by seniority according to our union contract. The Director of Nurses' now has decided to deny my vacation ( I'm top in seniority), due to if mine was granted she would have to deny other new employees. She just gave it away! Our union is dragging its feet, I don't know what to do. This is unheard of and unfair! I need help! Is she some super power who can and will always decide on vacation according to HER wants, not a contract or seniority?
