Generally revise public sector unions law

This bill revises Montana's labor laws to restrict how public sector employees and their unions can use public resources for union activities. It prohibits government agencies from using public funds to support labor organizations and bars public employees from receiving paid time off for union work, except under specific conditions where unpaid leave is allowed or personal leave is used with strict oversight. The law also requires detailed reporting and reimbursement processes when employees use compensated leave for representational activities, ensuring public funds are not indirectly used for union purposes. Additionally, the bill updates existing rules of conduct for public officers and employees to further clarify restrictions on using public resources for private or organizational business.
