The problem presented by this case is difficult—difficult because we are asked to provide a rigid definition of “regular rate” when Congress has failed to provide one. Presumably Congress refrained from attempting such a definition because the employment relationships to which the Act would apply were so various and unpredictable. And that which it was unwise for Congress to do, this Court should not do. When employer and employees have agreed upon an arrangement which has proven mutually satisfactory, we should not upset it and approve an inflexible and artificial interpretation of the Act which finds no support in its text and which as a practical matter eliminates the possibility of steady income to employees with irregular hours. Where the question is as close as this one, it is well to follow the Congressional lead and to afford the fullest possible scope to agreements among the individuals who are actually affected. This policy is based upon a common-sense recognition of the special problems confronting employer and employee in businesses where the work hours fluctuate from week to week and from day to day. Many such employees value the security of a regular weekly income. They want to operate on a family budget, to make commitments for payments on homes and automobiles and insurance. Congress has said nothing to prevent this desirable objective. This Court should not.
