… as is that. It’s unlawful discrimination and you could be hauled up for it. If that’s an actual written company policy a tribunal would have you for breakfast.
From the personneltoday website:
Under current UK law, discrimination against employees or job applicants on grounds of sex, race, disability, sexual orientation or religious belief by employers is outlawed. However, there are no laws that directly prohibit discrimination against smokers.
The above is from 2004, however I’ve found other references from 2018 which still support this. I also remember reading an article a while ago where someone tried to sue their employer as they let her go when they found out she was a smoker when their job advert stated only non smokerts. She lost her case as the ruling was that the company could employ only non smokers.
Of course my info may be a little out of date so if the law has changed in the last couple of years then I’ll be happy to be corrected.
