As overtime costs rose dramatically at D.C. Fire and EMS, the city’s top fire official approved more than $20,000 in bonuses for some of the leaders in his department, according to financial figures obtained by NBC Washington. “I gave bonuses to four assistant chiefs and one civilian,” Fire Chief Gregory Dean told NBC Washington. “We’ve been working very hard for the last year-and-a-half or two years, and I felt I needed to acknowledge the hard work that they did.” These are the first bonuses handed out by Dean since he took over the department in 2015.
