The reason I ask is because I was in a hotel last week downroute + was told that there were no non smoking rooms cos they didint have any at the hotel + smoking is allowed throughout. They said they would send an air purifier up to get rid of the smell but it didnt work - I ended up opening the window - even though i was told not to cos its a high rise building + slept in my coat cos it was so cold. The manager of the hotel said that rooms share the same vents so if someone next door was smoking it would be even worse. I complained to my manager when i got back + was basically told to put up with it. I spoke to the union who said to tell work that it might cause me to go sick downroute - i did + was told it would be a performance issue. My room stunk! Didn't get much rest cos I tried to stay out of my room as long as poss. Looked in my manual where it says "suitable accommodation" should be well ventilated. I have put this in writing + will hand it in tomorrow!
