Work shutdown falling on a holiday

Dear PAO,

I work in a garment factory as a sales assistant. Our yearly inventory for two days was scheduled on Maundy Thursday and Good Friday, which are both regular holidays. I asked our management if we would still receive our holiday pay despite the shutdown, during which we were not required to work. However, the management replied that only the workers involved in the inventory would be paid their holiday pay and premium. Did the management violate the labor laws on such a policy?
