Union leaders launched on Wednesday a concerted campaign that would counter what they claimed as emerging hostile environment in the workplace area, which they fear could be worsened by a likely Coalition win on 2013.

In a meeting held Wednesday in Melbourne, ACTU union executives called attention to rising job insecurities for Australian workers, a trend that they believe would not be reversed under a federal government at the hands of the Liberal-National Coalition.

In light of such alarming concerns, ACTU bosses said it will begin to implement additional levies of $2 per union members starting September 2012 through July 2015.

According to The Australian, the ACTU war chest is expected to raise $3.6 million each year and around $14 million by the end of the collection period over the next three years.

It is no secret that ACTU intends to use the campaign fund to keep federal government power at the hands of the Australian Labor Party and deny Opposition Leader Tony Abbott's bid to take the prime ministership from Prime Minister Julia Gillard, or whoever will lead Labor in the 2013 national election.

In a resolution issued by ACTU, union bosses warned that Mr Abbott appears to be harbouring plans "to give employers more flexibility (similar to take-it-or-leave-it individual contracts) and to scrap penalty rates."

"The federal Liberal Party has not revealed its industrial relations policy and continues to allude to attacks on workers' job security," the ACTU declaration was quoted by the News Ltd publication as saying.

ACTU is gravely concerned that with Mr Abbott at the helm, the federal government will re-embrace the Work Choices employment mechanism introduced by the Liberal Howard Government but was largely dismantled when Kevin Rudd and Labor swept to power in 2007.

"Workers are facing increasingly hostile employers ... We have seen with disputes where employers are using aggressive tactics ... rather than genuinely negotiating with workers and their unions," the ACTU resolution read.

Union leaders were convinced that this early, Liberal-National state governments, which in the past elections have defeated Labor governments most notably in New South Wales and Queensland, "attacking public sector workers and aggressively cutting services that workers and their families rely on."

ACTU has assured that funds to be collected from Australian workers will be used up in support of their interests.

The Coalition, however, scored the union workers' initiative, which it characterised as last-ditch efforts by Labor to save the party from certain annihilation come next year's election.

ACTU launched its campaign amidst the low poll numbers that bedevil the leadership of Ms Gillard over Labor, which lately has become restive anew with speculations of another leadership spill.

Talks on the possible return of Mr Rudd to lead Labor anew were ripe though Ms Gillard and key Labor figures have been insistent that the government was not distracted at all and remains focus in "governing ... and getting the big things done."
