The Claim:
Cashiers at a retail chain alleged that their meal periods were short and interrupted because they were regularly called back to work before the end of their break. The time clocks were set up so that once an employee clocked out for a meal, she could not clock back in for at least 30 minutes, making it impossible for the time clock data to reflect these violations.

Our Findings:
To test the validity of these claims, we linked the cash register data that tracks sales transactions to the time clock data to see if cashiers were actually working during the time in which they were clocked out. Instances of such behavior were infrequent and restricted to a small number of employees.

This analysis helped defeat class certification.
