The Confederation of Trade Unions (CTU) on Sunday called for pay increases of no less than six percent for Hong Kong workers next year.
They said employees should be paid more because of decent local economic growth and strong corporate earnings.
CTU chairwoman Carol Ng argued that a failure by employers to offer such increases would hurt staff morale.
She also said that wages have lagged behind productivity growth.
For example, private-sector pay in the second quarter of this year rose 1.7 percent year-on-year, while Hong Kong posted an almost 4 percent increase in real GDP growth.
The confederation's Lee Cheuk-yan told RTHK's Jimmy Choi that such small pay rises can hardly lift people's living standards.
"We create the prosperity, we create profit for the employer and economic growth, but we are not really improving our livelihoods," Lee said.
