sentences:  Section 11(c) of the Act imposed upon the employer, not the worker, the duty to keep proper records of wages, hours and other conditions and practices of employment.Where the employer has failed to keep accurate or adequate records, Justice Murphy argued, the law does not deny recovery on the ground that the employee is unable to prove the precise extent of uncompensated work.Such a ruling, Murphy noted, would create a strong disincentive for employers to keep any records at all and shift the burden back onto the employee.
