County employees’ jobs could be on the chopping block and a double-digit property tax increase could be in the offing after the Rockland County Legislature voted 9-8 Tuesday night to reject the county executive’s budget proposal, which would have temporarily increased local sales taxes by a half percent. Despite the tremendous loss in sales tax revenue, the majority called the proposal “premature” and a burden on families that have seen their jobs cut back or cut entirely. In a statement, Legislature Chairman Alden Wolfe said the focus should be on economic development and finding ways to keep shoppers from crossing the border into Bergen County where the sales tax is lower. Rockland County Executive Ed Day slammed the vote, saying in a statement yesterday that hundreds of county employees’ jobs are now at risk, and a double-digit property tax increase could be next. The legislature also shelved any movement on the Sain Building and property, which Wolfe said would be on a future legislature agenda.
