The National Institute for Occupational Safety and Health has agreed to rehire staffers on programs benefiting firefighters, after the Department of Health and Human Services canceled the World Trade Center Health Program, the National Firefighter Registry for Cancer and more. That’s according to the International Association of Fire Fighters, whose president won the concessions after weekend talks with Health and Human Services Secretary Robert F. Kennedy Jr. However, the relief might be temporary, as many of the NIOSH programs still have termination dates scheduled for June.
