On the vaping indoors topic, I'm yet to hear a good reason to disallow, especially in designated areas. If firmly disallowed, I would think it would be "because we said so" and rather cut to the chase in this thread's discussion with what I believe makes most sense and is doable. But, in reality, I believe most companies executive staff would at least pretend to be open to consideration that their policy is perhaps an extreme position that needs to either be made more solid or is open to change. My challenge, assuming it is allowed and they appear open, would be based on scientific data, reasoning and what other things the company does allow that people are not paid to do (i.e. chit chat), which I can find annoying, sometimes, at a job when I'm busy doing work. As noted on this thread, I'm yet to work for a employer or even hear of one where employees never ever engaged in something they were not paid to do (i.e. chit chat). FWIW, since age 16, I've always left a job on my own terms.
I think there's a lot of good reasons why management would at least consider it. How many hours a day are wasted on that chit-chat, not to mention going outside once an hour. A lot of employers allow access to the internet. They know people can do it anyway on their cell phone when nobody is watching, and it keeps us happy. We just have to convince them vaping isn't the same as smoking. That's not a big hill to climb. Ask for a vaping room as a starter. If they can see it would increase productivity and not annoy too many other people, why not. People have to ask though and keep the subject on the table, or nothing will ever happen.
Sooner or later some company is going to do it, and establish a precedent. Maybe a company with a vaping CEO.
