A NSW Liberal MP will defy his leader's direction not to stand in the way of Labor's bill to kill Work Choices.
Federal Opposition Leader Malcolm Turnbull has said Work Choices is dead and that the coalition accepts Labor's mandate to abolish the Howard government's industrial relations regime.
He has said the coalition won't oppose the legislation but reserves its right to move amendments in the upper house following a Senate inquiry.
But Liberal backbencher Alby Schultz says he will vote against the bill in its initial form, and will not support the bill when it returns from the Senate unless it addresses his concerns.
"Whilst the Australian people may have given the Rudd government a mandate for further workplace relations changes, I don't believe for one minute that the Australian people have given the government or the unions the right to return our workplaces to the bad old days of union domination," he told parliament on Monday.
Mr Schultz said his main concern about the bill was its green light for unions to enter workplaces and inspect non-union employees' wage records.
"I find it totally reprehensible that, after the introduction of this bill, a union will have the right to enter a workplace and demand, among other things, the production of records pertaining to the wages of non-union members, even in workplaces where the employer and employees have previously agreed that they don't want unions," he said.
Mr Schultz said he was concerned exemptions from unfair dismissal laws for small business would be removed under Labor's bill.
He said compulsory bargaining and arbitration for low-paid workers could turn into industry-based bargaining and arbitration.
"I can only deduce that the introduction of this bill is a way to insert union-dominated dogma into all businesses and return compulsory union membership," he said.
