I requested a few days off next month and it's been denied because of a religious observance taking place at the same time. I've been told I can't take any holiday until this period has ended. I checked the holiday calendar and no one else has any holiday booked for this time, yet my request has still been denied. I would be more understanding if it was an actual religious holiday but the vast majority isn't, just a few days at the end which is not when I requested my holiday for.
I've been at my job for a fair few years and never been told that I can't take holiday off during this time before. I was just wondering if this is even legal?
