Unions say the Queensland government is preparing to sack more public servants.
Attorney-General Jarrod Bleijie has introduced to parliament a range of workplace reforms that will dramatically cut redundancy entitlements for public servants.
Redundancy payouts will be capped at 16 weeks under changes the government says will simplify the awards structure for government employees.
Mr Bleijie says the reforms include safety nets for core conditions, but unions say they are reminiscent of John Howard's controversial WorkChoices laws.
Queensland Council of Unions president John Battams says the capping of redundancy payouts signals another round of public service job cuts.
"Why would they be doing this if there weren't going to be any redundancies?" he told AAP.
Payouts for public servants who have been in the system for 30 to 40 years will be reduced from a year's salary to just 16 weeks pay, Mr Battams said.
Mr Bleijie has assured workers there will be minimum safety nets for conditions, including leave provisions.
He says the current system is too complex.
"There are more than 100 industrial awards and agreements covering state government employees, which have created an administrative nightmare, stifled innovation and impeded service delivery," he said.
But Mr Battams says the government's push for "simplification" is a smokescreen to strip away workers' rights.
Unions are also alarmed at other new laws that impose new limits on compensation, and force unions to give 24 hours' notice before entering work sites.
"All of those things are designed to reduce peoples' rights and we are very concerned they're going back to what John Howard introduced in the 1990s," Mr Battams said.
The reforms will apply to more than 300,000 public servants working for state and local governments.
The state government has shed more than 14,000 public service workers since its election in March 2012.
The public service union Together said the changes meant workers would only be able to negotiate on wages, not conditions, through enterprise bargaining.
Furthermore, the Queensland Industrial Relations Commission would lose some powers on non-wage matters.
"It's WorkChoices mark II in Queensland, as the ability for the independent umpire is completely gutted, the awards system is gutted and the enterprise bargaining system is gutted," Together secretary Alex Scott said.
