A former assistant fire chief in Brewster who was expelled for using a racial slur against fellow firefighters has filed a $10 million federal lawsuit against the department and is seeking reinstatement. William J. Ratajack Jr., who was booted from the volunteer department in August, admitted in his Jan. 2 lawsuit that he uttered the "N-word" at two white firefighters during a July tirade. His lawsuit claims the targets didn't hear the slur and points out that they weren't even black. Ratajack, 47, said he served a 30-day suspension and was expelled after a hearing he was not informed of nor allowed to participate in. Ratajack claims he was denied due process and expelled for expressing himself on department protocol and procedure. He is suing the fire department, its board, the fire district and several individuals.
