At least 25 part-time firefighters in Maplewood are expected to lose their jobs in a matter of months. The fire department is planning to transition to a new system where the community will be served only by full-time personnel. While the move will help position the department to better respond to an increase in emergency calls, firefighters said it could have been handled differently. Maplewood Chief of EMS Michael Mondor said the administration reached the decision after commissioning a year-long study. The change means eliminating 25 part-time positions and adding six full-time positions.
