I was chatting with a rota rooter plumber, and He told me that they work mostly off of commission and that after they have been with the company for a while, You have to 'finance' your own van. when there is no 'calls' then they get paid something like $7 an hour, but the rest of the calls you get the money when you go out. Ive never heard of a company making you buy a 'van' to work for them. What do you think of this?? Is this common practice??
