As more companies look to be more transparent on their pay practices, they should expect to find that some employees are more satisfied with their salary than others. According to a recent survey from Robert Half, while 49 percent of workers feel their paid fairly, 46 percent disagree (and 5 percent actually admit that they think they’re overpaid).

In addition, the survey looked at compensation sentiment by age, gender and location. Interestingly, the 18-34 group had the highest percentage of those feeling overpaid (8 percent), and not surprisingly, more women report feeling underpaid than men.

Robert Half offers a few insights into why employees may feel underpaid, including outdated compensation plans and workers comparing their salaries to those of their peers or new opportunities offered by recruiters.

Whatever an employee is paid, Paul McDonald, senior executive director for Robert Half, reminds employers that salary doesn’t equate to worker satisfaction. “Professionals earning a healthy salary may still feel undervalued or underappreciated for their contributions,” he says. “Pay alone does not guarantee employee satisfaction or happiness. Organizations need to offer solid benefits, perks and incentives, along with a positive corporate culture, to attract and retain top performers.”
