I used to do these shops. But when they added the phone calls and more material to scan and send, whith shop numbers on the covers and a longer report, and only added a dollar, I got angry.
They also added a question: Are there any other comments you want to make?
I thought, why would I bother to make more work for myself and give comments, when they are not paying me for it?
I wrote in the comment section, that I thought they should not require more work for less pay.
After that, I did not see the shops on my list of availables anymore. I recently asked one of the schedulers about it and she told me the client asked to remove me because I made "not nice" comments about them. Well, shopeprs beware, you are not allowed to complain. If you don't like the pay, just say no.
