In a world where innovation cycles are measured in weeks and technology allows people to make their voices heard almost instantly, long terms of office that are two, four and six years are out of place. The current draft of the Uniting Amendment sets terms at one year for both Senators and Representatives, and limits members of the Senate and House to three terms. The term and limit for President remains unchanged at two terms of four years each, however, the Amendment makes it a little easier to remove a President from office. So the maximum time that someone may serve in Congress is six years (three in the House and three in the Senate). There is also a cap on the total number of years that a person may be employed by the government, which includes office-holders. That cap is ten years. (A person may voluntarily contribute their expertise to the government after that, but they can't be employed or hold an official position.)
Shorter terms with term limits help the government to more closely reflect the will of the people.
