This bill addresses pay fairness for federal employees and District of Columbia government employees who serve in the D.C. National Guard. Currently, when these employees receive National Guard pay, that amount is deducted from their regular federal or D.C. government paychecks, resulting in no additional compensation for their service. The legislation eliminates this reduction, allowing National Guard members to receive their military pay without having it offset against their regular government salary. The bill applies retroactively to the period from May 29, 2020, through December 26, 2021, meaning affected employees could receive back pay for that time period. This change primarily impacts federal workers and D.C. government employees who have served as National Guard members during or after the specified timeframe.
