A recent Florida law establishes a minimum member threshold that unions must meet
A new state law in Florida that was recently implemented starting in July threatens to shut down any public sector unions in the state that do not have at least 60% of the company’s workforce in the union. The law, titled SB 256, requires public sector unions to meet this threshold of union workers, or the unions will be decertified. The measure also bans the deduction of union dues directly out of employee paychecks, and this requires unions to re-enroll existing unionized workers in a new dues payment system. Unions are claiming that the measure is targeted at unions that do not support the governor’s agenda, as other public unions that represent police officers and firefighters are exempt from the requirements. The governor states that SB 256 will give more control to workers, and allow them to receive their full paychecks.
