The FLSA requires employers to keep records on wages, hours, and other items, as specified in DOL recordkeeping regulations. Most of the information is of the kind generally maintained by employers in ordinary business practice and in compliance with other laws and regulations. The records do not have to be kept in any particular form and time clocks need not be used. With respect to an employee subject to the minimum wage provisions or both the minimum wage and overtime pay provisions, the following records must be kept:
Records required for exempt employees differ from those for nonexempt workers. Special information is required for homeworkers, for employees working under uncommon pay arrangements, for employees to whom lodging or other facilities are furnished, and for employees receiving remedial education.
Not having proper record keeping will certainly place you at a disadvantage when defending an FLSA lawsuit. Don't make a costly mistake. Invest in a time clock or some printer paper and keep track of your employee's time!
