If your job doesn't include handling money or being responsible for other people's safety, why would your employer drug test you?

Depends. Some of the businesses clients may require that their vendors do drug testing. For example - I was Litigation Manager for a big law firm. Even tho the legal staff (paralegals, legal assistants,etc) never met with clients, some of our bigger clients required that anyone who may come across their information be drug tested. So we had to do random tests every 3 months. Most of our bigger clients had that requirement.

I don’t agree with it. Somebody could have gotten high 2 weeks ago and could pop hot today…even tho it has no affect on their work. It’s kinda dumb
