Want the biggest pay rise? Then become a 'boomerang' worker and go back to your old employer

While "quiet quitting" is getting a lot of attention, some workers are returning to their old jobs.

"Boomerang" employees who rejoin their former employer scored pay rises of up to 28% in the first four months of the year, according to new research by Visier.

The average increase in the number of workers changing jobs is 10%.

Three million employee records were analyzed. "Boomerang workers can use their knowledge of a company as well as their external experience as leverage for higher salaries", according to a CNBC report.

More than a third of external hires between January and April of this year were "boomerang workers" who returned 13 months after they left. 40% of them got management roles above their level.

According to Visier's research, people quit because they couldn't see opportunities to progress with their employers.

Due to a lack of workers, positions are going unfilled and critical projects have been delayed, which makes it a good time to ask for a raise rather than resign.

If companies want to retain their talent, they need to give raises and promotions at least every two years.

According to data from Visier, working relationships are one of the main reasons why people return to work.

The skills of a manager in the first year can't be overstated.

In the first year, managers should engage new hires in the company's culture and social networks.
