US wage growth decelerated slightly in May, according to data from Glassdoor. However, recruiters, as well as many healthcare and retail jobs, experienced faster-than-average wage growth across the US and in each metro covered by the reports.

The annual median base pay in the US grew 2.1% year over year in May to $51,159, down from the 2.4% revised pay growth in April and marking a four-month downward trend since US pay growth peaked at 3.1% in January.

As the US economy hits full employment, recruiters saw the biggest year-over-year pay gains in May at 7.4% growth to a median base pay of $51,216, indicating that companies are relying more on passive candidates to fill jobs, putting recruiters in high demand.

“Great recruiters know how to find and entice the right candidates for open positions, it is something of an art,” Andrew Chamberlain, chief economist of Glassdoor, said. “Having an eye for screening candidates and good judgment about who will or will not work for a position is becoming an increasingly valuable skill in a tight labor market.”

In nine out of the 10 metros tracked by Glassdoor, the pace of pay growth in May slowed compared to April. Only San Francisco saw the rate of pay growth accelerate, up to 2.3% year-over-year growth in May from 2.2% growth in April.

“The US continues to experience a slight softening in wage growth during the first half of the year,” Chamberlain said. “However, 2.1% is still decent growth and is higher than what we saw in 2015 and 2016. It remains above the rate of inflation, which indicates that on the whole, workers are getting ahead. The job market continues to be fast-growing, and we are seeing big wage gains for many jobs, especially in the retail and healthcare industries.”
