A rail union has said it would do a no-strike deal to prevent any walkouts during the 2012 London Olympics, BBC News has learnt.
The RMT wants an attendance bonus for its members
It could mean members of the RMT getting an increased hourly rate covering the duration of the Games.
BBC London's transport correspondent Andrew Winstanley said transport chiefs will not agree to the deal this early.
Organisers of the Olympics in Sydney made a similar pact with unions to pay workers an extra $4 an hour.
The RMT's general secretary Bob Crow told BBC London: "People will tell you the Sydney Olympics was one of the smoothest running, public transport wise.
"What they had done was put an attendance bonus in place where it gave a benefit to people to come to work, to make sure the Games run smoothly and give the company flexibility on the running of the services."
When asked what would happen if Transport for London (TfL) did not agree to it, Mr Crow said: "I imagine if our members don't get the same as other groups of workers have, we could have difficulties."
A statement by London Underground Limited said: "London Underground is working to deliver the best possible transport network for the 2012 Olympics and Paralympics.
"We are constantly working with all employees and trade unions to deliver a safe, reliable and clean Tube service, every day."
Mr Winstanley said this year TfL is to try to get a separate five year pay agreement with all their unions, which would take them up to 2011.

I wont get paid any extra for coming to do my job, why should they? It's blackmail by the unions and it must be against the law.

Bob Crow wants an 'attendance bonus' for RMT members during the Olympics to avoid a strike. Is an 'attendance bonus' not also known as 'pay', 'salary' or 'wages'? Don't they get that already?

A "no-strike" deal??? They shouldn't have to be paid not to strike! It seems that not a month goes by without a tube/rail strike. I know it's going to be a busier time for the rail/tube lines during the Olympics but being paid extra for going to work? You certainly wouldn't get that at any other place of work! What they should do is put in bonus scheme that will only be paid out based on their own performance during the Olympic games to see whether their work rate justifies the extra pay.
No. Not when they already the highest paid public servants in the country and get 52 days holiday a year. Usual greed from the RMT.
I think that the idea of being blackmailed into giving people money to go to a job they already get paid for is unbelievable. We have 6 years before the games - don't give in to Bob Crow, hopefully by 2012 the unions will have a spokesperson with some sort of moral code who recognises that this is not the way to win concessions or goodwill. Also, why should anyone get extra money just to arrive at work - I thought that was what a salary was for? Worst comes to the worst I am sure there are plenty of people in London or even Europe who would love to have a job and be able to provide for their families. If tube workers can't be bothered to go to work - give their jobs to people who want to.

This is ridiculous, the workers are paid to work. They should not expect to be paid a premium for working during the Olympics. I wish I could demand more money for going to work during our busiest times.
