Relief for employers and the tribunal service came last week when a House of Lords ruling cancelled out an estimated 3,000 claims for sex discrimination.
The cases have all been adjourned pending the final outcome of the long-running Seymour-Smith and Perez case.
This tested the two-year service period required to qualify for protection from unfair dismissal.
The claimants argued that the cut-off point, since reduced to one year, represented indirect sexual discrimination against women because men work for longer periods.
But in a final judgement the Lords ruled that the statistics did not convincingly bear this out, and that it is justifiable for the Government to have a service requirement so as to encourage recruitment.
