Union boss Paul Howes is sick of opinion polls and regrets being poll-driven at the time Kevin Rudd was dumped as Labor leader.

Federal Labor's primary vote stands at just 30 per cent, down five points since December, according to the latest Herald/Nielsen poll published in Fairfax newspapers.

Support for the coalition is up four points, taking its primary vote to 47 per cent - its highest level since just after the carbon tax began in July 2012.

On a two-party-preferred basis, Labor's support is at 45 per cent, well behind the 55 per cent for the coalition, according to voter feedback on the direction of second preferences.

It doesn't appear to faze Mr Howes, the national secretary of the Australian Workers' Union (AWU).

"I am not worried about constant polls that change from week to week," he told ABC television on Monday.

He was reminded he didn't appear so sanguine about such samples of public opinion when he was one of the so-called "faceless" men who dumped Kevin Rudd as leader in 2010 after a series of bad polls.

"Absolutely. You just heard me eat humble pie," Mr Howes said.

"I regret that I was one of the people that used to engage in this constant useless chatter on various opinion and chat shows around the country.

"I am sick of it, I am not doing it any more."

ACTU secretary Dave Oliver wouldn't be drawn on leadership speculation.

"When we're out and about in workplaces around the country, we don't have workers talking to us about who's dining with who or the leadership speculation," he told ABC radio.

"We know that the Gillard government has been doing a good job out there and hopefully will continue to do so."
