Compensation rose a median 6.96% for top executives at publicly traded staffing firms in North America, according to a new report. However, the compensation actually decreased a median 12.64% among executives at Europe-based staffing firms and by a median 4.19% for firms based in other parts of the world.

The report was done by Staffing Industry Analysts in conjunction with data provided by Equilar, an executive compensation solutions firm, based in Redwood City, Calif.

It looked at the two highest-paid executives at a selection of 60 publicly traded staffing firms, search firms, job boards, PEOs and online staffing platforms. The median percentage increase in compensation reflects executives who have been at their firms for two complete years or more and where information was available.

Here’s a list of the 10 most highly compensated executives at these firms in 2015:

Robert Half International Inc. Chairman and CEO Harold Messmer topped the list. ManpowerGroup Inc. Chariman and CEO Jonas Prising came next, followed by Tegna Inc.’s Gracia Martore. Tegna’s business include the CareerBuilder website and nonworkforce related web properties such as Cars.com and local television stations in the US. The only executive at a Europe-based firm in the top was Adecco’s former CEO Patrick De Maeseneire.

Total median compensation at the 29 North American firms tracked was almost $1.7 million in 2015.

In comparison, the total median compensation at the 26 publicly traded European firms was $617,438 in US dollars. And for the five publicly traded firms located outside North America and Europe, the median total compensation was $310,472 in US dollars.

As a note, compensation includes base salary plus bonuses, stock awards, option awards and other compensation.
