Editor’s Note: In a surprise ruling just before Thanksgiving, a federal judge from the Eastern District of Texas issued an opinion stopping the DOL’s new overtime rules from taking effect on Dec. 1.

Millions more American workers will be eligible for overtime thanks to a new U.S. Department of Labor rule. Under the previous guidelines, certain salaried workers who made less than $23,660 per year were entitled to receive overtime when they worked more than 40 hours a week, even if they weren’t hourly. Under the new rule, most salaried workers who earn less than $47,476 annually will be eligible for time-and-a-half when they work more than 40 hours each week. And the estimated four million workers who will become eligible represent just the beginning — every three years, the pay levels will automatically update.

Although the Obama Administration and Labor Department Secretary Thomas E. Perez hail the change as a benefit to workers, the implications could be extremely negative for many employers. In fact, the U.S. House of Representatives voted to postpone the date the new regulations take effect by six months, and several lawsuits have been filed to postpone it. A delay would provide “breathing room for retailers large and small struggling to comply with the changes during their busiest time of year,” said National Retail Federation (NRF) Senior Vice President for Government Relations David French in a statement.

Whenever it takes effect, it will have a significant impact on employers, workers, and the U.S. economy. Employers should prepare now for whatever happens, in order to minimize the financial cost of complying and the legal risks of failing to comply.

The New Rule

The 1938 Federal Fair Labor Standards Act (FLSA), guarantees a minimum wage to almost all employees in the United States, and requires employers to pay overtime when employees work more than 40 hours in any work week. There are, however, several exemptions to the overtime requirements. Employees who are exempt from overtime requirements under federal law most often fall under one of five exemptions (the so-called “white collar” exemptions): executive, administrative, professional, computer employees and outside sales.

Under the FLSA, in order to classify a position as exempt, generally that position must pass both a salary and a duties test. Currently, the salary test requires a weekly salary of $455 per week ($23,660 per year). The duties test depends upon the exemption, but typical duties to look for include: directing and supervising the work of others; the authority to hire, fire, and promote; non-manual work; exercising independent judgment and discretion; advanced knowledge in a field of science and learning through prolonged course of instruction; or sales performed away from the employer’s place of business.

Under the new rule, the salary test will more than double from $455 per week to $913 per week ($47,476 per year). There is no salary test for outside sales.

 The DOL estimates that the initial change to the income threshold will make 4.2 million salaried workers newly eligible for overtime pay.

Challenges to the Rule

In September, the U.S. House passed the Regulatory Relief for Small Businesses, Schools and Nonprofits Act by a vote of 246-177, mostly along party lines. The bill would postpone the new overtime pay rules until June 1, 2017. A similar bill has been introduced in the Senate, but its chances of passing are questionable. Even if the bill is passed, Obama has said he will veto it.

Twenty-one states have filed a lawsuit to stop the new overtime rules.

More than 50 business groups also filed suit in the same court claiming he government exceeded its authority and violated the Administrative Procedure Act.

“The DOL went too far,” said Randy Johnson, senior vice president of labor, immigration, and employee benefits for the U.S. Chamber of Commerce, in a statement. “We’ve heard from our members, small businesses, nonprofits, and other employers that the salary threshold is going to result in significant new labor costs and cause many disruptions in how work gets done.”

The court granted a request by the plaintiffs to combine their cases. The parties have filed motions asking for a preliminary injunction to prevent the rules from going into effect while the legality of the rule is fully litigated.

Next Steps

Most employers are hoping that the lawsuits will be successful. However, they should also prepare for new overtime regulations with the following steps:

Review Your Workforce Now and Gather Information

The rule change will require employers to take action. Now is the time for employers to conduct a thorough review of their workforces, in order to gather the information necessary to make informed decisions. This review should be more substantial than simply identifying what exempt employees currently make less than $47,476 annually. Considerations that should be examined include the number of hours potentially affected exempt employees currently work, potential salary compression issues, pay differences across regions or state lines, and the potential effect on incentive payments or similar bonus payments.

If employees are reclassified as non-exempt, they’ll be required to accurately keep track of time worked. This will affect the employee’s ability to go above-and-beyond, perform outside of regular work hours, or put in the extra effort to secure additional training.

If your employees routinely perform work at home, including answering emails, this should be reviewed. Once an employee is reclassified as non-exempt, routine and minor work at home can constitute work time, and can expose your company to liability.

Consider Workplace Morale When Making Decisions

Employers should be cognizant of workplace morale and its impact on productivity when deciding on any solution. Simply re-designating previously exempt employees as non-exempt can have significant negative effects. First, many employees will view this as a demotion, especially supervisors who have worked their way up from the crew.  Second, previously exempt employees will likely lose work schedule flexibility, benefits that are provided only to exempt employees, and perhaps equally important to many, their status in the workplace.

Consider Alternatives

Employers could also explore alternative methods to help limit the impact of the new regulations, such as the fluctuating work week schedule or moving employees to non-exempt salaried status. However, before making any changes, employers should ensure that they are complying with both state and federal law, which often have different requirements. And employers should remember that alternative arrangements, other than traditional non-exempt or exempt status, often lead to inadvertent violations of the FLSA.

Provide Clear Communication

Whatever steps a company chooses to take to address the new rules, clear communication with affected employees will be paramount. Employees who are reclassified as non-exempt will require a clear explanation why, as well as an explanation of new requirements, such as keeping track of their time. In addition, some employees may need to be let go, some jobs may need to be restructured, and some duties may need to be absorbed across several jobs — all of these operational and other changes will need to be carefully explained.

The changes to overtime regulations will have a major impact on many organizations from a financial and management perspective. It will take close monitoring and proactive work to make sure employers stay in compliance.
