Up to 100 union members are preparing to rally at the Southern Cross Club, following their refusal to accept a pay increase offer from the Labor government of 2 per cent for each of the next four years.

Unions ACT secretary Kim Sattler told Fairfax Media that members from 12 unions would gather inside and outside the club to rally against the ‘‘insulting’’ offer.

‘‘Basically the bargaining has been getting nowhere,’’ she said.

‘‘I’ve never had this level of anger and unity among members while I’ve been in this job. It’s not fair-dinkum bargaining from our point of view.’’

Ms Sattler said members of unions such as the United Firefighters, the Community and Public Sector Union and the National Union of Workers, would be on site from 8.30am.

‘‘The only other place we’ve got to go after this is protected action ballots and three unions have already applied for these,’’ she said.

The Australian Nursing Federation will not be part of Saturday’s conference but is preparing to launch protected action if a compromise is not reached with the ACT government on Thursday.

The union has put a range of savings measures to the government to try to improve the wage offer, but ACT secretary Jenny Miragaya said there had still been no movement in the government’s position.

The federation has given the government until Friday to reach a compromise or it will apply to Fair Work Australia for protected action ballots.

‘‘I would be very happy if they accepted the compromised position,’’ Ms Miragaya said.

‘‘If not, on Friday we intend to contact Fair Work Australia about launching the protected action process.

‘‘The members are not prepared to accept a 2 per cent pay offer.’’

Meanwhile, nurses in Queanbeyan have joined statewide strike action over concerns regarding staff-to-patient ratios in New South Wales hospitals.
