Top employees may be getting restless.

According to Salary.com, 65 percent of employee respondents plan to look for a new job in the next three months. What’s more, the percentage of employees who describe themselves as "very likely" to leave their current job increased more than 50 percent in the past year, to 38 percent of employees, Salary.com reports.

Sure - employees may stay with you when times are tough. But as the economy picks up, watch them leave for greener pastures. This is especially true for top talent.

So do the best people want great pay or great working relationships?

The want both.

Insurer MetLife’s annual Employee Benefits Trend Study finds that employees’ top consideration when deciding to join or remain with an employer is "the quality of co-worker and/or customer relationships," followed by the opportunity for work/life balance and "working for an organization whose purpose/mission I agree with."

Compensation research firm Salary.com, meanwhile, finds that inadequate compensation is the top reason dissatisfied employees cite for leaving. No opportunity for advancement is second, followed by no recognition for work, according to the company’s 2005-2006 Employee Satisfaction and Retention Survey.
