No. Overtime-eligible workers are not required to punch a time clock. The FLSA requires that employers keep certain records for each nonexempt worker. That’s so workers can be sure that they get paid the wages that they earn and are owed. Employers have options for accounting for workers’ hours – some of which are very low cost and burden. There is no particular form or order of records required and employers may choose how to record hours worked for overtime-eligible employees. For example, where an employee works a fixed schedule that rarely varies, the employer may simply keep a record of the schedule and then indicate the changes to the schedule that the worker actually worked when the worker’s hours vary from the schedule (“exceptions reporting”).
For employees with a flexible schedule, an employer does not need to require an employee to sign in each time she starts and stops work. The employer must keep an accurate record of the number of daily hours worked by the employee, not the specific start and end times. So an employer could allow an employee to just provide the total number of hours she worked each day, including the number of overtime hours, by the end of each pay period.
The Department has material available to help employers figure out what method of recording hours works best for their workforce.
