Instead they will seek the three per cent pay rise requested by unions.

ETU officials met with staff at the Orange depot on Wednesday morning over the offer proposed for the next three years.

After the meeting ETU deputy secretary NSW and ACT branch, Allen Hicks said the dispute could lead to the workers going on strike.

"Absolutely, if that's what's required," he said.

Mr Hicks said there were about 50-60 workers, mostly members of one of three unions including the ETU, at the workplace.

He said the unanimous vote by workers on Wednesday followed a similar vote at the Tamworth depot earlier in the week.

Mr Hicks said ETU officials were travelling around the state this week to speak to members to get their views on the latest enterprise bargaining negotiations.

He said the company's offer was 'inadequate' allowing for rising costs of living.

A union statement said it was fighting to secure TransGrid workers a 'fair pay rise', as the cost of housing and other essentials were climbing in regional communities.

"In Orange, house prices have increased by 3.2 per cent over the past 12 months and the weekly cost of rental houses has surged by 9.1 per cent over the same period," it said.

"Despite this, Transgrid, a multi-billion dollar company, part-owned by a Hong Kong infrastructure firm, has failed to make an acceptable offer over 11 months of Enterprise Bargaining Agreement negotiations."

Mr Hicks said the union wanted the company to 'get back to the table' for further negotiations.

He said the federal government was forecasting the consumer price index would reach 3.5 per cent in the next year but TransGrid was offering only two per cent.

Mr Hicks said the company was also asking TransGrid to absorb a 0.5 per cent superannuation payment which effectively reduced the pay rise to 1.5 per cent.

Transgrid was contacted for comment by the Central Western Daily. It issued a short statement.

"We value our people and their contributions and we are continuing to talk to them about a fair pay rise," it said.

TransGrid operates the high voltage electricity transmission network in NSW and in the ACT.
