Should people who smoke be denied jobs because they are at greater risk for many serious illnesses why or why not?
No. That would exclude millions of people and be highly
discriminatory. There are also many other people who are at great
risk of contracting serious illnesses and to be seen to be fair,
they would have to be excluded too, resulting in millions more
people being out. You would be excluding some brilliant people from
the workforce, as just because someone has an illness, that doesn't
mean they cannot contribute at a high level to the workplace. Many
exceptional people have illnesses and many people in perfect health
are not good workers. There would be many other problems trying to
impose such a policy, so there is absolutely no way it could be
done.
