I worked in the warehouse, sorting parcels and letters by post code. It could be kind of boring sometimes but you can bring headphones and play your own music which is really nice.
Being on your feet the whole time can be a paid so make sure to wear comfortable shoes.
The people are really friendly and there's a canteen with a restaurant that functions Monday to Friday, not just vending machines.
I had the Christmas temporary weekend job that was great for a little extra money over the holidays and there was room for overtime which was great, and being away from customer service was a nice break.
Only downside was that people would throw the parcels over your head into the correct containers which wouldn't be good for someone who's very flinchy or nervous.
Good pay, bring your own music, dont have to talk to anyone
