Except as provided in paragraph (2) of this subsection, and notwithstanding any statutory or regulatory deadline in any grievance procedure listed under subsection (a) of this section, a grievance under subsection (a) of this section shall be initiated within 20 days after the failure to pay occurred. If the failure to pay is not known to, or discovered by, the employee within 20 days after the failure to pay occurs, a grievance under subsection (a) of this section may be initiated no later than 6 months after the date on which the failure to pay occurred. Subject to paragraphs (2) and (3) of this subsection, if a grievance is initiated in accordance with subsection (a) of this section, an employee is entitled to wages and damages unless the wage is withheld as a result of a bona fide dispute.

The damages under paragraph (1) of this subsection: may not begin until at least 1 regular pay period has elapsed since the employee was not paid the employee’s full wage due for a pay period; shall increase per pay period by 30% of the wage that the appointing authority failed to report; shall continue until the pay period when the appointing authority reports the missing wages and damages, if any, to the Central Payroll Bureau; and may not exceed 3 times the amount of wage due that the appointing authority failed to report for a pay period.
