Mr Norris' move to introduce a no strike agreement for tube workers was launched ahead of the latest strike ballot result by the Rail, Maritime and Transport workers' union (RMT).
Under Mr Norris' blueprint, workers and employers would have 100 days to negotiate a better pay deal in exchange for forsaking their right to strike, which he claims costs London business £30m a day in lost revenue.
His attempt to woo London voters entails a new employment contract for tube staff together with an independent arbitration for future pay deals overseen by an independent panel.
Mr Norris' intention to "put an end to the kind of wildcat strikes that have caused misery for passengers" is part of a concerted effort to topple the popular mayoral incumbent Ken Livingstone at the poll in June, first revealed in an exclusive interview with SocietyGuardian.co.uk earlier this year.
The Tory candidate denied his plans were tantamount to eroding tube staff's employment rights.
"I'll make the unions an offer they ought not to refuse," he said. "I will get [RMT general secretary] Bob Crow and other union representatives round the negotiating table to sort this problems once and for all. I intend to be completely fair and open with the unions. I have no wish to remove employment rights in any way but a long term agreement that is fair to both sides is overdue."
Later today, the RMT will announce the result of the ballot over the sacking of five Metronet Tube maintenance workers after empty beer cans were found in a cabin at Farringdon, North London.
The five were fired by a disciplinary board last December despite the company's failure to link any of them with allegations of illicit drinking on London Underground property, the union claims.
The ballot is expected to give overwhelming support for strike action, which will result in 24 hour stoppages on several underground lines.
Mr Norris has not yet posted a copy of his plans to the RMT.
But the union's regional officer Bobby Law gave the plans short shrift: "We would never agree to such a thing as a no strike agreement, for the simple reason that there are injustices that affect our members and we have to protect them, particularly around safety issues," he said. "This is both for our members and for the travelling public."
