in some professions if you want to work you have to play by the rules like it or not.
You used the word "professions". I've seen very little, if any, grousing and complaining from people with professional jobs who are making good salaries 60K, 80K or more a year, in professions that they worked hard to get the education to get in the first place. I imagine that people who have families to support and mortgages to pay and/or went thru 4-8 years of higher education to get there don't "throw it all away" in order to vape against workplace rules.
You can do that stuff if you are living in Mom's basement, or flitting from minimum wage job to minimum wage job (which is what happens to employees who are under the delusion that they are the ones who get to "call the shots".

As for this case, vaporizers are used for other things. If the bus driver was using a vaporizer in a bus that would be filled with children, he's an idiot. He also lied to the kid, saying the smell was from the heater. Buses are school property, therefore, an extension of school property. This would be no different than a teacher vaping inside the classroom. This is all common sense.
Parents don't want their children to walk thru or sit in a haze of vapor on a school bus. And, I have to agree, they shouldn't have to.
At any rate, the woman would never have gone to the news if the school had taken some accountability, basiially, they claimed they couldn't keep track of all their bus drivers.
That statement alone would make me *wonder* if i should put my kid on a bus in that district......a district who admits they don't have the resources to "monitor" what bus drivers are *doing*???? Yikes. This is like a train wreck waiting to happen. There are already incidents on the books where bus drivers, both school and municipally employed, have talked on their cell phones, loaded their ecigs with ejuice while driving, vaped while driving, etc.
If nobody is monitoring the drivers, then that is left up to the children themselves in this district? Yikes again. That is what happened here. Bus drivers are carrying the lives of children, they HAVE to be monitored.
BAsically, all they should be doing while on the job is driving, and being watchful for the safety of the kids. Not practicing their habits, whether that be using a cell phone, vaping, vaporizing whatever, eating a sandwich, etc. Next it will be reading girly magazines while on the bus waiting for the children to load, or worse.
Like I've said here for years, there seems to be a distinct "disconnect" in the workforce today, who don't seem to realize that they are on the clock while somebody is paying them. Instead, everybody seems to think the workplace is their personal living room, where they get to do whatever they want.
We once had a receptionist who was the first person clients would interface with when they walked thru the door. For some reason, she thought clipper her nails and such, at her desk, (once even putting on nail polish) was "okay". Revolting. She was let go pretty quickly. This wasn't a factory, it was a professional office LOL Again, people don't seem to understand the difference between their living room and the workplace. We once had a guy clip his toenails in his cubicle. There is really something wrong with people.
