Roughly two-thirds of the firefighters in South Tucson have now indicated they will resign by the end of the month, leaving residents of the small city wondering if there will be enough personnel to adequately respond to emergencies. A former South Tucson firefighter claimed that due to the mass resignations there are two days next month where only one Fire Department employee is scheduled to work on a specific shift. The claim could not be independently verified. City Manager Sixto Molina said it was too early to tell which firefighters will be working specific shifts next month, noting the city is working quickly to find replacements and persuade some firefighters not to leave the department.
