The Danbury City Council has signed off on a new contract with the firefighters union.  Firefighters will continue to operate under 24-hour shifts and not see a salary increase this fiscal year.  There is a caveat though, if the City's finances improve, there could be wage increases.  Raises are included in the next two years of the three year agreement. Firefighters are protected from layoffs or furloughs under terms similar to the recently approved contract for the Danbury Municipal Employees Association.
