Union Carpenters and their allies in are preparing for Days of Action events to bring attention to tax fraud in the construc- tion industry. The Carpenters union will hold 5 events in 4 states to highlight this crisis. Construction industry tax fraud is costing U.S. taxpayers at least $2.6 billion a year, according to an estimate done for the United Brotherhood of Carpenters (UBC). Some 1.2 million construction workers are paid off the books per year, while another 300,000 are called indepen- dent contractors when they are really employees.
