UNION leaders will steer clear of using tomorrow’s Labour Day march to protest against privatisation, but the acting Queensland Premier Paul Lucas can expect to be heckled and jeered.A Queensland Council of Unions spokeswoman, Tanya Reeves, said the theme for the march was ”Working for a better life”, although each union was free to have its own theme during the walk.Ms Reeves said several unions were likely to vent their frustrations about the Queensland government’s privatisation plans and the Health Department’s payroll bungle.”We expect about 30,000 for the march … [that] is about standard,” she said. ”Some unions [have a] sub-theme or campaign against issues that are affecting them.”Issues such as health and privatisation, I’d imagine, would be featured during the march.”It will come down to common courtesy regarding Paul Lucas.”I’d imagine there may be some heckling from the crowds as they march.”Mr Lucas will head the march, along with QCU president John Battams and QCU secretary Ron Monaghan, and outgoing ACTU president Sharan Burrow. Ms Reeves said the Builders’ Labourers Federation would be the first union to take to the streets in honour of its centenary celebration.Mr Monaghan said the focus of the Labour Day march would be the ”big-picture” gains made during the entire history of the union movement.These would include highlighting successes such as the eight-hour working day, four weeks’ paid leave and compensation for injuries.”We’ve always seen Labour Day as an opportunity to reflect on the successes of the past as well as to look ahead [at] what we’re still fighting for,” Mr Monaghan said.”Regardless of the battles that still lie ahead, Labour Day is a day for celebration.”The march will begin at 10am at the corner of Wharf and Turbot streets in the CBD and will conclude at the RNA Showgrounds at Bowen Hills.Ms Reeves said guest speakers would address the Labour Day crowd, and there would be children’s rides, a barbecue lunch and live music would also at the showgrounds. ”Labour Day is a major family day and we try and stick to that,” Ms Reeves said.
