My manager is refusing to give me my remaining holiday entitlement. My current post is a 6 month contract. I have tried to take up all of my holiday till the end of my contact. But I still have about 30 hours left over before my contract. Can she refuse to pay me for my holiday left over entitlement? She is demanding that I take ALL of my holiday before my contract ends. I have tried my best but I cannot as I already have a few booked appointments. What can I do?
