evidence: Democratic Gov. Tony Evers and the GOP-controlled Legislature have spent months blaming each other for the agency’s shortcomings as they stalemate in addressing many of Wisconsin’s challenges. In January, Evers called a special session of the Legislature to overhaul the state’s unemployment system. The Legislature gaveled in as required by law, only to immediately adjourn until Wednesday, when it advanced a bill to start the process of replacing the state’s antiquated claims system. The Evers administration largely attributes DWD’s shortcomings to its antiquated, inefficient computer system for processing claims — relying on 1970s-era technology that previous administrations never upgraded. Republicans agree that Wisconsin should replace the system, but questions loom about how and when the state will pay for it. [...] But software upgrades won’t fix everything, as other states have learned. Michigan’s technological overhaul a decade ago resulted in false allegations of fraud against tens of thousands of claimants — leaving many in financial ruin. Agency staffers did not verify whether the automatically flagged claims were actually legitimate. That same system backlogged early in the pandemic.
