Cosmopolitan magazine is leading an online protest via Facebook and Twitter today, urging women to fight against the current 15% pay gap.

At 3.55pm, a time chosen due to it being 15% less of the average 9-5 working day, the magazine will begin the protest using hashtag #4Kequalpay spend it YOUR way, encouraging women to retweet and comment on how they would spend the extra average £4k they are missing out on each year from their salaries. All tweets and Facebook posts include a link to the Cosmopolitan Equal Pay Petition, to be delivered to David Cameron later this year.
