Workers will finally be bringing home the bacon — salaries are about to break out of a decade-long slump.

US professionals nationwide will soon be taking home their biggest paychecks, as the tightening labor market and economic recovery will spur companies to confidently raise salaries and pay bigger bonuses, according to a new study by Willis Towers Watson Data Services.

“Employers tend to pay more when they feel confident about the future,” said Murray Gunn, an analyst at Elliott Wave International. “This survey certainly reflects an ebullient mood among business leaders.”

Employers haven’t paid an increase like this since 2008, when the financial crisis torpedoed company coffers.

The Willis Towers Watson survey reported big gains for the most-coveted jobs: Top-rated professionals in finance and corporations were awarded average increases of 4.6 percent this year, 70 percent higher than the 2.7 percent picked up by the average worker.

Average pay increases for non-management workers will reach 3.1 percent in 2019, compared with 3.0 this year, the Willis Towers Watson study projects. The data are based on historical, current and next year’s projected salary budget increase percentages.

The average salary bump, though seemingly small, comes amid huge surges in payouts for numerous categories of US workers, as revealed by other studies.

For example, salaries for registered nurses rose by 4 percent in the past 12 months, customer service managers notched an increase of 7.4 percent and delivery drivers saw gains of 5.4 percent.

A rise in the minimum wage is also contributing to the pay bump nationwide, according to analysts.

“After a decade of consistently flat pay raises, we are witnessing a slight uptick as companies are feeling pressure to boost salaries, given the low unemployment rate and the best job market in many years,” said Sandra McLellan of Willis Towers Watson.

But, of course, adjusted for inflation — and factoring the vast expansion in the ranks of low-paid workers nationwide — it’s not a picnic for everyone.

Today’s average US wage has about the same purchasing power as it did 40 years ago, according to Drew DeSilver, an expert at the Pew Research Center. Most gains have flowed to the top tier of workers, like bankers and dealmakers on Wall Street.

Among the cream of the crop, the top tenth of the curve, real wages have soared a cumulative 15.7 percent, to $2,112 weekly — nearly five times the usual weekly earnings of $426 of the bottom tenth, according to DeSilver.
