The only paper on this topic "Labor Market Outcomes of Postal Reorganization" by D. Richard Froelke, the former manager of collective bargaining for the U.S. Postal Service was published in the book Mail @ the Millennium, edited by Edward Hudgins and published by the Cato Institute. This paper provides more detail on labor negotiations through the year 2000. Most importantly, this paper indicates that the problems in wage and benefit levels reflect the continuation of contract provisions and an understanding of pay compatibility that existed in the 1970's that has been nearly imposible to remove in either a negotiated or arbitrated settlement. The list of arbitrated settlements above, which are described in more detail in the Mr. Froelke's article illustrates that eliminating wage premiums and restrictive work rules in arbitration did not occur even after the Postal Service began presenting significant evidence to an arbitrator regarding the need to control compensation costs.
Finally, it is worth noting that many who argued prior to passage of the Postal Accountability and Enhancement Act that steps were needed to constrain wages made recommendations that are not much different than contract provisions in the APWU contract. For example, Michael Schuyler, Senior Economist at the Institute for Research in the Economics of Taxation made the following recommendations in the paper, "How to Bring Postal Compensation into Line With The Private Sector," a paper published in 2003.
- Increase postal compensation at the rate of inflation until the postal pay premium is reduced or eliminated.
- Increase postal pay more slowly than increases in an index of private sector labor costs to gradually reduce the postal pay premium.
- Restrain postal wages when the postal worker quit rate is very low or the number of qualified people seeking postal jobs is very high.
- Vary postal wages by geographic region.
- Increase the use of part-time and temporary employees who would receive market or above-market compensation but less of a pay premium than full-time career employees.
