The New York City Fire Department is set to reduce staffing in 60 engine companies from five firefighters to four.
With a summer marked by several intense heat waves, sources tell NY1 that medical leave levels have risen above 7.5 percent in the last 30-day period.
That is the threshold which contractually allows the city to reduce staffing to help control overtime.
It is the fourth time in seven years that the Department will reduce manpower.
The Uniformed Firefighters Association says the city has miscalculated the way it computes medical leave, because the agency does not give firefighters who go home sick in the middle of a tour credit for having worked some portion of their shift.
A judge blocked new hiring, too.
