A poll of union members will close tomorrow on wage agreements covering more than half of all Tasmanian public sector workers.
If Community and Public Sector Union members support the agreements it will end two years of negotiations with the Tasmanian Government.
However, correctional officers plan to step up their industrial action from tomorrow with a ban on overtime.
CPSU general secretary Tom Lynch said the agreements included the main public sector agreement covering about 15,000 public sector workers and those covering allied health professionals, radiation therapists, ministerial drivers and legal practitioners.
"The Agreements include wage rises totalling around 7 per cent over the next three years and improvements to working conditions such as parental leave and superannuation," Mr Lynch said.
"Most importantly agreement has been reached on some transformative changes in work practices that will improve career opportunities and allow public sector workers to use the skills built up over their working life to deliver even better services to Tasmanians.
"Job security in the public sector will be improved with the government agreeing to review the use of fixed term employment and convert many positions to permanent."
Mr Lynch said feedback from CPSU members during information sessions showed strong support for the agreements.
However, correctional officers will tomorrow ban working overtime.
"With the Tasmanian Prison Service heavily reliant on correctional officers doing overtime on top of their full-time roles, prison management may need to fill front-line posts on Friday to ensure even a basic level of services can be maintained," Mr Lynch said.
"Industrial action will escalate further next week unless a fair offer that is not contingent on correctional officers accepting untrained support staff in correctional officer posts is made."
