Unions say the NSW government's "war on wages" has escalated, as the premier says unions involved in illegal strikes should face the "hardest fines possible".
The government plans to impose maximum fines of up to $55,000 for the first day of illegal industrial action and $27,500 for each subsequent day.
The penalties will also see unions fined $110,000 for the first day of an illegal strike, and $55,000 on each following day.
