I live and work in Colorado. I know that pot is legal here.
I work on a golf course owned by the city. We operate a lot of heavy machinery, often within a few yards of golfers. One of my coworkers, who also happens to be my trainer, smokes pot constantly while we work. He doesn't put it down except to refill it during our 8.5 hour shift. We will be moving 15 mph on absolutely massive lawnmowers, and he will be steering with one hand, doing zigzag patterns (we are supposed to be perfectly straight) as a result, and holding a container full of lit pot in the other hand. This terrifies me, as he is extremely unpredictable when he starts smoking, but I am also exposed to these drugs and have not even been asked if that is acceptable. Even worse, young children are often on the course and are exposed without any warning or parental approval.
I don't know what the laws regarding this sort of issue are, but it seems wrong to subject so many people to a dangerous drug without at least warning them beforehand. It seems even worse that I am forced to learn from somebody who is constantly stoned, as I cannot understand him most of the time and do not know if he is teaching me correctly.
When I get in to work tomorrow, I'm going to try to talk to my boss about this. Is there anything I should know about the rules and laws related to this subject before I start that conversation? Am I allowed to request a different trainer for this reason?
