Labor uses women's day for penalty case

Opposition Leader Bill Shorten has used International Women's Day to bolster his case for protecting penalty rates.

Mr Shorten said women were more likely to be working in retail and hospitality jobs affected by the Fair Work Commission decision to cut Sunday penalty rates.

"If Malcolm Turnbull wants to do one good thing for women on international women's day, he will join with Labor and stop the penalty cuts right now," Mr Shorten told reporters in Melbourne.
