I don't know what to do and need some advice. My supply job has been difficult from the start. A colleague was rude to me leaving me in tears The kids have no routine or structure. The children work on paper not in books . The children rip paper up or throw it around the room.The work set is either too hard or repeats earlier lessons. Had a horrendous lesson earlier this week. Kids refused to follow seating plans and we're openly rude. Rang agency in tears. I think I want to leave but am scared to. Need some sensible advice please
