Volunteering in a charity shop is the worst move to make. The manager's treat volunteers like ****. Personally, I wouldn't touch charity shops with a barge pole ever again in my life. If you want to be a volunteer in a charity shop, here's a lowdown on the one's to avoid, Cancer Research UK, Oxfam, British Red Cross, Mencap, the British Heart Foundation and a few other's. Cancer Research UK and Oxfam are the one's to avoid like the bubonic plague. I'd personally avoid charity shop work if I were you, the manager's suck the life out of you as a volunteering dogsbody and moan like hell if you don't glue yourself permanently to their respective shop. Steaming clothes in a charity shop is awful as you're expected to get every crease out of the clothes you steam. Sorry to be negative, I hope you find a good charity shop to be in. I wish you luck.
