Echoing the police union’s recent criticism of city management, the Janesville firefighters union is not happy with how city officials handled the latest round of contract negotiations. The two sides reached an agreement last week for a three-year deal that will last through 2021. But Janesville Fire Fighters Local 580 President Jason Daskam said the city has effectively severed a productive working relationship with the union. The conflict goes back to spring, when the city eliminated firefighters’ ability to wash their personal vehicles at fire stations. The firefighters could use city water but needed to bring their own soap and towels, Daskam said. The perk was included in the union’s personal amenities clause, something Daskam said dates back decades and has never been an issue before. That clause does not include a list of amenities.
