Since labour ready is a temporary labour agency they don't have reliable work every day, but that is standard of any temporary agency. Labour ready provides single day placements and pays the same day after the job is completed, on a first come first serve basis.
Employers through labour ready vary widely, as there is no screening of the work environment. Some of the worst people I have worked for hired through labour ready, as well as some of the best. Labour ready staff are very friendly and helpful, and we're willing to work with me when I was living far from the office (I have transportation).
