His remarks came after Mr Shapps accused the union of "damaging people's lives" after thousands of commuters were affected last week due to the biggest rail strike in the UK in more than three decades.
Train services were crippled again on Saturday due to another 24-hour strike by thousands of workers in a bitter dispute over jobs, pay and conditions.
Urging Mr Shapps to engage in talks, the union boss said: "So if Grant Shapps wants to be constructive that’s what he can do. He needs to tone down the rhetoric and get on with his job, which is to settle this dispute."
Last week's strikes were called as part of a dispute over pay and conditions on the railways, after the government asked train operating companies to find savings through “modernisation”.

“So if Grant Shapps wants to be constructive that’s what he can do. He needs to tone down the rhetoric and get on with his job, which is to settle this dispute,” the union boss said on Saturday.

Brandon Lewis has been criticised for referring to train drivers’ salaries while discussing the RMT rail strike - just a day after prime minister Boris Johnson did the same thing.
The Northern Ireland secretary appeared on Sky’s Sophy Ridge On Sunday programme where he said train drivers were earning between £56,000 and £70,000.
He added that the dispute - which prompted industrial action on Tuesday, Thursday and Saturday - is an “issue between the employer and unions” and that people want to see a resolution.

Scottish Labour leader blames UK government for rail strikes
05:58 , Alisha Rahaman Sarkar
Scottish Labour leader Anas Sarwar said the rail strikes were “entirely of the UK government’s making”.
“It is important to give solidarity to striking workers at picket lines and it is important to recognise that this is a crisis entirely of the UK government’s making,” Mr Sarwar told Channel 4.
“The workers don’t want to strike, the unions don’t want to strike, the public doesn’t want the strike, and all of them demand better of this government. And I think Grant Shapps needs to stop playing the political games, stop the culture war here, get around the table and get a deal (sic).”

Labour MP Nadia Whittome has donated £2,000 to the Rail, Maritime and Transport (RMT) union’s strike fund.
“These rail workers are leading the way for all workers. They’re the ones who need a pay rise, not MPs,” Ms Whittome said.
When I was elected I pledged to share my MP's salary with my community.
So in solidarity with @RMTunion members in the East Mids, I've donated £2,000 to their strike fund.
These rail workers are leading the way for all workers. They're the ones who need a pay rise, not MPs.

Christmas presents could be affected by the series of rail strikes due to disruption of the supply chain, months before the festive season.
According to reports, over 600 freight trains run in the UK every day, carrying goods such as TVs, clothes and decorations.
“As the year goes on, freight gets busier, particularly containers, so that’s a big worry. The China surge will come in – and those ships are sailing now. It always gets busier into August, particularly when we start seeing Christmas stuff come through,” an industry figure was quoted by The Mirror as saying.

A senior Labour figure has toughened the party’s stance ahead of a “summer of discontent” over falling pay by saying he does not “support strikes” – triggering a backlash.
David Lammy, the shadow foreign secretary, said he “categorically” does not support a walkout by BA check-in staff, dismissing their call for a 10 per cent pay increase.
Calling it “very sad when any union calls its members out”, Mr Lammy also said: “I don’t support strikes,” before adding: “I support the right to strike of course.”
