A new survey from the Society for Human Resource Management shows that the vast majority of HR managers review whether their employees are exempt from overtime pay regulations. But the regularity with which they assess varies greatly and a small percentage pay no attention to the issue at all.

In anticipation of a proposed Department of Labor rule that will raise the salary threshold for workers exempt from overtime pay regulations, the exemption status of employees is a particularly sensitive issue for SHRM, which has strongly opposed the rule change, saying the threshold is being raised too high.

The bill would also include a provision to adjust the salary threshold every year. After more than a decade at $23,660, the threshold is more than doubling to $50,440 for salaried workers in 2016, but will likely increase with the rate of inflation thereafter. That means it’s important for HR managers to monitor their positions to understand how much the company can anticipate to pay in overtime, if at all.
