Making history, creating PTD raisesIn 1911, Wisconsin became the first state to adopt a comprehensive worker’s compensation law that was upheld as constitutional. The money for worker’s compensation checks comes from worker’s compensation insurance companies and from employers who are self-insured for worker’s comp. About 21,000 people annually receive Wisconsin worker’s comp checks, the vast majority of them for a temporary period. How PTD raises are decidedThe process that determines whether PTD raises are granted is not unlike the bargaining that an employer and a union do to reach a contract. The process typically takes months of negotiations, said John Dipko, the council’s non-voting chair and administrator of worker’s compensation for the state Department of Workforce Development.
