I HAVE the RIGHT: Holiday for the student

─ Good afternoon, "MK-Sootechestvennik"! Thanks for your support. I arrived from Kazakhstan and now I study to Germany. My family cannot finance me, I have three more sisters. I study and I work at the enterprise as the student. I can distribute the working hours more or less freely; generally in firm 2-3 days, during vacation ─ 4-5. Tell, whether I have the right for holiday? May I not take and ask it that to me it paid (we in firm have such practice that pay holiday)...
