Josh Tauburer has the analysis, drawn from the recently released “House of Representativeâ€™s Statement of Disbursements of the House, July 1, 2009 through September 30, 2009.”
His answer? Chief of Staff and Legislative Director salaries do not vary based upon a Member of Congress’s tenure in office. However, Staff Assistant, Legislative Assistant, and District Director salaries do vary.
Analyzing Josh’s numbers, it looks like a Staff Assistant can expect a 5% pay increase each year. Legislative Assistants, however, can expect on average only 1.1%, and District Directors can expect only 0.6%.
