By changing from an every two week, or 26 pay checks per year, to a twice monthly, or 24 pay checks a year, model every government employee will see an 8% increase in their monthly take home pay for ten out of the twelve months of the year without increasing spending. This is accomplished by spreading the twice annual third check across all the months.
In addition to not increasing spending this change in the long term will, albeit modestly, increase efficiency and reduce payroll associated cost for managing the federal workforce. Finally it aligns pay with the monthly household bill cycles allowing easier planning of household budgets.
