The records must be kept for three years in the premises where an employee works except each employer subject to sections 177.41 to 177.44, and while performing work on public works projects funded in whole or in part with state funds, the records must be kept for three years after the contracting authority has made final payment on the public works project.

(c) The commissioner may fine an employer up to $1,000 for each failure to maintain records as required by this section, and up to $5,000 for each repeated failure. This penalty is in addition to any penalties provided under section 177.32, subdivision 1. In determining the amount of a civil penalty under this subdivision, the appropriateness of such penalty to the size of the employer’s business and the gravity of the violation shall be considered.

(d) If the records maintained by the employer do not provide sufficient information to determine the exact amount of back wages due an employee, the commissioner may make a determination of wages due based on available evidence.
