Sounds like Congress is trying to hide something with this one or you're trying to get more time off, not that you work more than a half a year for a full year's over-inflated salary! Do you think your bosses, the citizenry of the US are so stupid as to not figures this out! There isn't a corporation with a budget this size that would ever consider doing this! So NO! Leave it as an annual process and earn your pay! Maybe you could get some work done if you'd quit granting yourselves more time off every time you at working as few days as that even is at this point!
