Two-thirds (67 per cent) of North American men say they earn $55,000 or more, compared to just 39 per cent of women, according to a new survey by the Robert Walters Group.

The survey, which polled more than 6,000 employees, found 44 per cent of non-binary employees reported feeling underpaid, followed by 40 per cent of women and 26 per cent of men. More than half of women and 41 per cent of non-binary employees said they haven’t been offered a promotion within their current company.

Nearly a quarter (23 per cent) of women and non-binary respondents said their main challenge to wage progression was a lack of opportunities, whereas men reported that balancing work and personal commitments was their key challenge.

The survey also found while nine per cent of men said they’ve received a raise of between 26 per cent and 30 per cent in the last 12 months, fewer than half as many women said they’ve received the same increase.

Two-thirds (40 per cent) of men received $151,000 or more in equity compensation in addition to their base salary, compared to 25 per cent of women. Nearly a fifth (17 per cent) more men than women received bonuses that were in line with their expectations and more than half of non-binary respondents said their bonus wasn’t in line with expectations.

More than two-fifths (44 per cent) of non-binary workers said they don’t believe their organization takes active steps to be demographically representative and 39 per cent said they don’t feel their workplace is a safe environment.

“With women accounting for 51 per cent of the population, the case for addressing the gender balance issue in the workplace has long been discussed and the evidence for the business case for it well known,” said Coral Bamgboye, head of equity, diversity and inclusion at the Robert Walters Group, in a press release. “However, recent reports show us, at the current pace of change, gender pay equity is unlikely to be achieved in my lifetime or even that of my children.

“More needs to be done to address the systemic barriers and organizational issues that remain in place for women in many organizations.”
