There is new legislation coming into Ireland early next year, the dates have not yet been fully confirmed but Jan 1 is the kick-start date.
The laws are anti-smoking laws and have been much in discussion lately over here. The anti-smoking laws are more than likely being expanded into the workplace, which should bail the FR FO's !!
Unfortunately though, enforcement of this law will be the stumbling block.
BTW:
(I can't see how FR would have a clear out of a few FO's as mentioned previously, just cos someone has a grievance with a smoking captain, there are ways of confidential reporting )
