Women are effectively working for free for the rest of the year because of the gender pay gap, equality campaigners have said.
According to the Fawcett Society, it will take 60 years to close the gap at the current rate of progress.
Its report found that jobs women do are more likely to be low paid and they are less likely to receive a bonus or progress to the highest job in their organisation.
The society has called for more action from the Government and employers to tackle pay discrimination, job "segregation" and help to get women into senior posts.
An occupational illness is a medical condition caused by work you are doing, or have done in the past.
It may be caused by your work activities, or something you have worked with such as asbestos or chemicals.
Every year thousands of people are diagnosed with medical conditions caused by their work.
A 33-year-old medical researcher died from a cancer usually caused by asbestos, despite no history of being exposed to it, an inquest heard.
Rose Wharton died of mesothelioma at her Oxford home on 20 May, after being diagnosed in September.
Coroner Darren Salter said it was a "very unusual" case, because the illness usually only affects those who worked around asbestos for decades.
He told Oxford Coroner's Court he had never seen a case like it.
Most cases of mesothelioma are diagnosed in people aged between 60 and 80, according to the NHS.
