A revision to overtime rules from the U.S. Department of Labor is posing strategic challenges to employers.

Beginning on July 1, the Department of Labor will enact the first in a series of increases in the salary threshold that must be met for employees to be exempt from overtime pay under the Fair Labor Standards Act  or FLSA.

The government estimates that the July increase, and another set to take effect in 2025, will make 4 million workers newly eligible for overtime.
