Does this violate any OSHA or Department of Labor laws??

I work in what has become a cramped warehouse doing light industrial work. The extremes of cold, hot, and air quality are generally unhealthy.Proper heating,cooling and air circulation is not always made possible We use solvent based printers.This is an issue because the filter being used for the air is clogged and hasn't been changed in months.The cold recently got me sick.My employer had purchased a propane heater but has always lagged in getting more gas when needed. So the long and short is this: If the work environment causes sickness and you have sick pay,shouldn't you get it.I went to my doctor and was told it was a touch of the flu and provided my boss with a note. Here's what I expected to receive on my most recent check I worked 30 hours between Monday and Wednesday.I went in on a Thursday and had to leave an hour in because I felt so bad and it was in the 30's. I figured 7 +8='s 15 sick hours used. I got my check and it's for 30 worked and 10 sick. Whats wrong wih this $hit?
