Brendan Barber, general secretary of the Trades Union Congress, said: "We deplore any attack on maternity provision or protection against unfair dismissal." Paul Kenny, of the GMB union, said: "George Osborne, the man who is giving a £40,000 windfall to each of the millionaire elite, has announced more attacks on the least well-off in our society and on workers' rights."
Some business leaders warned that take-up of the scheme could be limited. Treasury sources admitted that big companies were unlikely to offer shares but estimated that the tax relief could cost £100 million by 2017-18.
John Wright, an employment law expert, said: "You can't agree to forgo your discrimination rights. If employees volunteer for this scheme, they could still take a case for race, age or sex discrimination."
Changing the rights stuff: How it would work
*Under the terms of the voluntary agreement, companies would be able to give employees shares in their business if, in return, they gave up a raft of employment rights. To encourage the scheme, no capital gains tax would be charged on any profit from the shares.
*Employees would be given between £2000 ($3901) and £50,000 of shares, but would have to give up their rights to claiming unfair dismissal, redundancy, flexible working and time off for training.
*Women would also be required to provide 16 weeks' notice of a date of return from maternity leave, instead of the current eight weeks.
*Legislation to bring in the new-type contracts will come in this year, with companies able to use them from April.
