How Do You Know What Companies Will Do Hair Folic Drug Testing..? Ie. Dal Tile/ Mohawk Ind.

I am searching online for a new job. I am currently employed at Waste Management. My current job is extremely demanding. My hours are from 5 a.m. Til sometimes 9 p.m. / 5 days a week. I have a new baby, and wife at home. I would like to start spending more time at home. So therefore I am seeking a job with shorter hours. I have found a few that meet the criteria, although I am interested in finding out what kind of drug screening they will be performing on me upon hiring. The company is Dal Tile.
