Protecting workers in pubs

Molly Finch writes: This is the last ditch argument used by the anti-smoking lobby at the suggestion of offering choice to pub customers, ie smoking or non-smoking pubs. Has anybody actually asked the workers in the pubs if they want protecting? I've worked in pubs and I would guess that 90% of bar staff are smokers and hate the idea of a ban. What on earth is wrong with a clear statement to the effect that this is a smoking environment, and if you choose to come here/work here you do so in full knowledge of the risks to your health?
