England's Shoreham Port has implemented several proactive measures over the past few years to balance the number of male and female staffers, but headway has not come easily.

These initiatives have improved the gender profile at the port of 120 workers to 80% men and 20% women — in 2018 only 15% were women.

"We've been making a couple of percent changes every year and it does add up," said Nicky Brown, people, communications and sustainability director.
