Smoking is a HABIT and not necessary for life...its not oxygen, food or water...its a habit. Thats it. So, yes people can work 12 hours, people can and DO choose to not smoke while at work or around others. These peoe DO have control.
Of course they CAN do the shift without smoking and they CHOSE to smoke. However a habit is just that, something that is hard to break which is why I said people would be hard pushed to go this time without smoking, not that they couldnt do it.
These people do have control yes but they also have choice and should be allowed to make that choice for themselves.
It's not just themselves who are influenced by that choice though.
It's easy for people to say, "oh, request a non-smoker then!" but in practice it's not so simple. What if there are only smokers available? What if asking for a non-smoker means you don't get the immediate care you need (e.g. replacement midwife in labour)? What if the smoker is offended and bitches to their colleagues who in turn act unprofessionally and don't provide the best service they should?
Also, why should someone have to go throught the potential embarrassment and awkwardness of requesting a non-smoker? My friend's OH had to really stand his ground before they would swap the midwife who stank of smoke for one who didn't. What if this was a woman labouring alone? Or with someone who couldn't stand up for her? Should she really have to have her brand new baby handled by a smoker? For some people, it's not easy to speak up so why should they even have to?
You would be hard pushed to find a nursery or a school that doesn't have some smokers for staff and in those situations you wouldn't be allowed to request someone else to teach your child or look after them. And if you move your child to a new nursery, what are the chances of them having smokers? There's no escape. Smoker's always go on about their right to choose to smoke etc and it makes no sense to me. What about a non smokers right to access healthcare that isn't contaminated by smoke toxins? What about a child's right to not have smoke breath breathed all over them?
I'm rambling now lol.
