Before the National Labor Relations Board issued its recent decisions in the Kentucky River cases, union leaders and activists predicted dire consequences — potentially stripping millions of workers, especially in the healthcare industry, of their rights to join a union. Unions, which are trying to attract more employees to their ranks, staged rallies and other events to draw attention to these cases.

But the decisions did not dramatically redraw the lines for determining which workers are considered supervisors and which are not. Instead, they provided guidance that will be helpful to employers and unions alike in determining the status of workers whose classification falls into the gray area between supervisor and employee. The analysis remains highly fact-specific and appears unlikely to create the dramatic effects predicted.
