Integrity Staffing Solutions, Inc. v. Busk

The Court held that post-shift anti-theft security screenings were not compensable under the FLSA because they were not 'integral and indispensable' to the workers' principal activities.

Time spent on activities that are not the principal activity the worker is employed to perform, and not integral and indispensable to it, is not compensable under the Portal-to-Portal Act.

Set the modern federal standard for compensable pre- and post-shift time. Several states (CA, NV) have since diverged and require pay for the same time under state law.
