Modifies provisions relating to leaves of absence for military service

HB 2940 protects public employees in Missouri who serve in the National Guard or military reserves by guaranteeing they can take leave for military duty without losing their job, pay, seniority, or benefits. It specifically allows up to 120 hours (38 workdays) per federal fiscal year for federal military service, while providing full leave protections for state duty under the governor's call. The bill requires employees to submit military orders to their employer as proof of duty and prohibits employers from discriminating against or firing employees for military service. Volunteer firefighters receive all protections except those related to monetary compensation.
