The NSW Industrial Relations Commission yesterday released the results of negotiations between union leaders and BlueScope over the company's plans to shed 800 Port Kembla jobs.

The 27-page agreement, which identifies 395 surplus wage employee positions across the steelworks, outlines how many and which jobs will be slashed in most departments.

It also confirms a one-off payment of up to $12,500 will be included in the final pay-outs to long-serving employees.

Union officials said the deal was a reasonable outcome after difficult negotiations.

Sixty-four jobs have been marked to go at the No 6 blast furnace, which will shut down as BlueScope exits the export market.

Slabmaking has also been hit hard, with more than 150 surplus positions identified.

The remainder of the losses are spread across departments, while the final number in refractories and logistics will be the subject of further negotiations.

The majority of the redundant workers will leave the steelworks before October 31 and the agreement will also be subject to a six-month trial period, with a review in April 2012.

Steelworkers will vote on the outcome of the negotiations at a mass meeting next Thursday at WIN Entertainment Centre.

Under the final arrangement, redundant workers will receive 14 weeks' pay plus 2? weeks' pay for each year of service and a one-off payment based on their tenure.

A payment of between $7500 and $12,500 will go to workers who have been at the steelworks for between 15 and 35 years, as long as their total package does not exceed two years' pay.

Union leaders are confident enough workers will apply for voluntary redundancy to meet the job losses, and even raised the possibility some workers could miss out.

"We didn't agree with their first lot of figures for the job cuts but obviously through the negotiations ... we've come to a fairly honest outcome," Electrical Trades Union's John Thornton said.

Unions expect the final number of job losses to be closer to 720 than the original 800.

Staff jobs are expected to make up the losses not identified in yesterday's agreement.

Yesterday, a BlueScope spokeswoman said the company would now move to the "implementation stage with the objective to complete this phase by the end of October".
