I work in an office where humidity is below 40% sometimes as low as 15%, I have seen the Occupational Health adviser and he has confirmed that this humidity will set of my asthma. He has advised a move to a more suitable office however there doesnt appear to be one and I am continuing to work in my normal office. Since Feb I have had 3 asthma attacks which have caused me to come home but my boss has said that these asthma attacks are due to a Chest infection I had in Jan not the humidity even though the office stats show the humidity was at its worse on these 3 occassions. I am due to return to work on tues and the boss has confirmed humidity is still below the 40%, seems that employers can do what they like, any advice? My union is involved but my boss doesnt take any notice of them!!!!
