Tennessee Coal, Iron & Railroad v. Muscoda Local No. 123
Headline: Dangerous underground travel counts as compensable work, Court affirmed, requiring employers to include miners’ portal-to-portal time in the workweek and pay overtime, affecting iron ore miners and mine operators.
Holding: The Court held that time miners spend traveling underground on company property, under employer control, is work under the Fair Labor Standards Act and must be counted in the workweek for overtime pay.
- Requires mines to count underground travel time as work for overtime calculations.
- Employers must pay time-and-a-half for excess hours that include underground travel.
- Shifts disputes from local custom to federal overtime rules in covered mines.
Summary
Background
Three iron ore mining companies asked the courts to decide whether time miners spend traveling underground between the mine entrance (portal) and the working face (where they drill and load ore) counts as work under the Fair Labor Standards Act. The dispute focused on hours worked between the Act’s effective date, October 24, 1938, and suits filed in April 1941. The companies relied on long-standing pay practices that measured pay on time at the face, while miners and the government argued travel underground was required, supervised by the employer, and hazardous.
Reasoning
The Supreme Court said the Act must be read broadly to protect actual work and that “work” includes physical or mental exertion done under employer control and for the employer’s benefit. The Court accepted findings about dangerous, supervised underground travel (crowded skips, long walks, poor air, heavy tools) and agreed that such travel is necessary to production. The Court rejected company claims that past customs or contracts excluding travel time could override the statute. It also noted the Wage and Hour Administrator’s view and some state laws counting underground travel as work.
Real world impact
The Court affirmed that underground travel between portal and face is part of the workweek and must be counted for overtime calculations. That means miners who worked more than the statutory hours including that travel were entitled to overtime pay for the excess. The decision shifts pay rules away from purely local custom toward the Act’s national protection for covered employees.
Dissents or concurrances
Several Justices concurred in affirming on the factual record. A dissent argued courts should respect established industry practice and collective agreements and cautioned against creating retroactive payroll liabilities without congressional direction.
