Walling v. Helmerich & Payne, Inc, 323 U.S. 37 (1944), is a US labor law case, concerning the minimum wage.

The employer, Helmerich and Payne Inc had the practice of paying workers more in the second half of the day than the first, so that overtime on weekends was calculated to the lower rate (clocked premiums) and could not be premium pay, so as to keep wages for overtime the average.

Justice Murphy, writing for the majority, held that clock premiums or rolled up pay cannot be treated as premium pay.
