Prison officers at Parklea jail in Sydney's west are striking for three days as they continue a campaign for more pay and better safety at work.
It's the third time the officers, who will rally outside the Parklea Correctional Centre at midday on Wednesday, have walked off the job in as many months.
Community and Public Sector Union NSW assistant general secretary Troy Wright says the jail near Blacktown has the worst record for serious assaults on prison officers in NSW and the second worst rate of assaults amongst inmates.
