Public servants at the Australian Taxation Office have voted to accept a new deal on pay and conditions with a landslide 83 per cent yes-vote announced on Wednesday afternoon.
More than 16,600 of the ATO's employees voted, an 84 per cent turnout in the ballot, which brings three years of sometimes bitter industrial strife at the vital revenue agency to a close.
Thousands of scientists, researchers and other workers at the peak science body the CSIRO also voted last week to accept a new pay deal after a dispute lasting several years at the organisation.
The landslide at the ATO came after workplace unions decided to either endorse the deal on offer, which features average pay rises of 2 per per year for the three-year agreement, or to not actively campaign against it.
But the main workplace union, the CPSU, said the three years of wrangling had been messy and unnecessary and that bad blood would linger for years among the ATO's massive workforce.
Feeling were running so high at one point during the dispute that senior managers had to shut down internal discussion boards being used by public servants to vent their fury at the pay offer on the table at the time, with one executive issuing a plea for calmt\.
Many employees, who have not had a general payrise since 2013, remain deeply unhappy that they will not get any back pay, which is banned under the Coalition's workplace policy.
Commissioner of Taxation Chris Jordan hailed the result as a "really positive" outcome for his agency while announcing the result on Wednesday.
"Our next step is to send our EA to the Fair Work Commission for final approval," the commissioner wrote in an all-staff email.
"Subject to that, the EA takes effect seven days after that approval.
"We can then pass on your initial pay rise of 3 per cent on the next available pay day after that approval.
"I would like to acknowledge the contributions made over the last three years and the collaborative approach taken between the EA team members, your unions and workplace bargaining representatives."
Both the Australian Services Union and the CPSU told their members at the Tax Office the proposed agreement was much better than earlier versions with many of the harsher elements of the Coalition's policy removed.
ASU official Jeff Lapidos said he too welcomed the result.
"The ASU welcomes the very high yes-vote," he said.
"It is the outcome of hard work by the ASU and ATO Bargaining Teams who delivered an enterprise agreement that maintains all employees' workplace rights and conditions of employment."
CPSU National Secretary Nadine Flood also welcome the end of the "messy dispute".
"This vote finally brings an end to this long, messy and unnecessary dispute in Tax, but it will take years to repair the damage that's been done to the trust and morale of staff," she said.
"Voting this time around was a hard decision for ATO staff, whichever way they voted, but ultimately they've recognised the bargaining progress made in recent months."
