"It's not that management hasn't been told that people aren't working; it's that they don't act on it," said Catherine G. Scott, president of Local 2187 of the American Federation of State, County and Municipal Employees, the union that represents the tax board's non-patronage workers.
"I don't think it's fair to say none of them work," she said. "The level of work varies greatly."
Board members say they stopped the worst abuses by installing a swipe-card system to track employees' comings and goings.
"Years ago, maybe they were ghost jobs. But that hasn't been the case for several years now," said board member Dintino, the former GOP ward leader.
He and other BRT members say the patronage workers handle many important duties that help evaluators, such as visiting properties and looking up records.
"They're the nitty-gritty," Dintino said. "They're the soldiers of this army."
