Time to take the stick approach to dealing with wage inequality?

According to Tania Branigan of The Guardian, "equality campaigners and trade unions have attacked a report into women and work before its publication because its 40 recommendations do not include any demands for legal changes such as mandatory pay audits."

In Wage inequality report attacked for failing to push for audits Branigan also warns that a pay and opportunities gap is damaging to the economy because previous measures have not gone far enough in tackling occupational segregation.

I just can't see compulsory audits happening under the current government and the Conservative party normally always avoids things of a compulsory nature. What is more, I don't believe the answer to the problem involves women doing what are termed as men's work, although that would help the problem somewhat. I honestly think that employers should be compelled to advertise how much they are willing to pay a new entry employee as this clearly where the problem starts, i.e. unless you are put on a transparent pay scale, or have very open colleagues, then most employees have little information to judge their situation on.
