RE: About one in ten people applying for most part time jobs can pass a drug test.
Where is this? Colorado where Marijuana is legal?
I have friends who manage Walmart, Target, Best Buy, Staples, McDonald's, Bojangles, and Walgreen's stores as well as a couple of non-franchise restaurants.
Believe what you like, but drug use is so widespread now it's the norm, not the exception these days. At least for people thirty years old and younger.
