If this is going to be a State or Federal Requlation than what is the union going to do for you? Nothing... The State and Federal Governments don't care if you are union or not. It's like driving a UPS vehicle and running a stop sign in front of a cop. UPS is not at fault and does not have to pay the ticket for your stupidity. If you have nothing to hide than why worry.
Exactly! For all those that are wondering IF the union should get involved, why not try reading the "National Master United Parcel Service Agreement"? Pg 81, Section 3.1:
"UPS employees subject to Department of Transportation
mandated (italics and bold mine) drug testing are drivers of vehicles with a vehicle weight rating over 26,000 pounds, requiring a CDL..."
This, by the way, is a contract that WE, members of the union, and UPS agreed to, voted on and signed (you DID vote on it, didn't you?).
Well, that let's all you PC drivers, PTers, office help, etc. off the hook, huh? Well, read on...
Sec 3.8
Reasonable Cause Testing
"Upon reasonable cause, UPS will require an employee to be tested for the use of controlled substances."
It goes on. You wanna read it? So, continue to recreate in the privacy of your own home (doing no harm to anyone else, according to you) and take your chances you ain't acting funny. I just hope you ain't driving your personal car, your package car or anything else in my direction or the direction of my family. And, oh, yeah, wonder if the union is gonna help you in THIS one!
