Yeah I started a workplace co-op program with my school at my local Staples and I really enjoy working their especially since I really like my supervisor. She's cool to me. Unfortunatley I'm worried I'll strain my back as my job is stocking shelves from the back to put on display. It began to hurt near the end of the day. Will I develop more back problems or is it because I'm not used to working hard? This is also in a way my first real work expirence. My dad is proud of me. so aside from worring about my back? I enjoyed day one. Did anyone of you guys enjoy your first day of work?
