Labor leaders from the Gulf States of Texas, Mississippi, Alabama and Louisiana will be holding a joint conference tomorrow to demand that President George W. Bush reinstate the Davis-Bacon prevailing wage Act. The law required that federal contractors’ not lower community construction wages less than $20,000 a year for skilled full-time work. In that region during clean-up government contractors have also received a pass on applying affirmative action standards for hiring and rules that stipulate the number of hours a truck driver can work have been lifted.
