As much as the following post will look like a retort to AttyPops, it is really directed at the less than politically aware vaper.
We don't have the "right" to impact air quality of others.
And yet we do, when exhaling CO2 into the air that other people will breath.
As a general rule, vape outside or in designated areas.
My general rule is vape everywhere with respect.
A place (private or otherwise) that has a rule in place of "no vaping here" has set back the idea of respect, or plausibly removed it from the table. With an employer and current politics surrounding this there are at least 2 roads to travel when such a rule goes into effect. The popular path is to follow that rule, if you know what's good for you, tread very lightly, look for other employment if that suits you, and never ever resist or even question the policy because it is their place and their rules. So be a good little peon and do as you are told until you find another place to work. The road less traveled is to resist the policy in a way that is strategic and not based on emotion. You'll know what this looks like for your particular situation if you take a few days, perhaps weeks, to contemplate such a strategy that actually has a chance of working. For me, in general terms, it does look like you vaping at work in places you are pretty darn sure you will not get caught. Not cause you need a puff and can't make it the whole day without one (heck vape zero nic if that jives with your strategy), but vape just to establish that "you all wouldn't even know if someone was vaping in this building. It is that discreet, that unnoticeable. If I lit a smoke or sprayed air freshener or passed wind, you'd notice. Vaping? Not so much or likely not at all." Bathrooms are generally a great place to start, but ought not be the only place that is tested. Other strategies beyond this ought to be implemented and the more comprehensive the overall strategy, the more thought through, the better, especially if you know the goal.
We can't go around spraying air freshener around constantly either. Neither can we vape just because we believe "it won't harm anyone". We don't have the right to "be obnoxious" just because we want to be. That's the "new norm" and it just isn't going back to the was it was in the 50's.
Can we go back to the 2012's?
This idea of vapers being obnoxious means that vaping anywhere indoors with respect is impossible for some people to understand. Even some vapers have trouble understanding this. Vaping with respect, consideration for others, is close to common sense. Vaping with idea of blowing huge clouds to fill up a small space, or with intent to blow it in a non-vaper's face is close to obnoxious. Passing a rule that says no vaping anywhere and justifying that on basis of clean indoor act is close to obnoxious. One of these positions seeks common ground, common courtesy. The other two really do not care what others think and also aren't initiated to foster mutual respect.
That said, any regulations against vaping outside are pure B.S. and (I would think) borderline unconstitutional...private property or not.
For all those that can make an argument for no vaping inside, I can (and have) make the argument for no vaping outside. The wind factor does mean you have no way of knowing where your exhaled vapor will end up. Hence, not so much pure B.S. and arguably worse than some indoor locations. Can still blow vapor intentionally into people's faces when outdoors. Can still be an obnoxious vaper if that is the desire, or lack of consideration for others.
Making prejudicial rules just for the sake of making them and copping an attitude is....bogus. But since it's private property, you're better off looking for a new job. I guess in the days of "at will employment" and "corporations are people too"...you can't do much because you don't have any rights...only the corporations do. It's all "good for business" and "creates jobs"...but you can't have one even if you vape outside. That's the rub.
IMO, the rub is that ANTZ operatives know they can count on gaining businesses (many indoor places) to restrict vaping as a societal practice. They know some businesses will go along with their thinking on this and/or they can capture all businesses via local or state ordinance that forbids vaping anywhere. The real rub is that some vapers will go along with this and not resist it, not realizing that offering no resistance does help make the case for no vaping in particular outside locations a viable position. This is already occurring in parts of the U.S. (laws where you cannot vape outside). The real rub is that vapers either are sure vaping is nothing like smoking or very much desire for it to not be treated like smoking, yet due to both smoker's guilt and lots of giving in to anti-smoking strategies, have managed to concede a whole lot of ground, for the pro-vaping position.
