FedEx Corporation (NYSE: FDX) is scheduled to discuss its fiscal fourth-quarter 2009 results tomorrow in a conference call at 8:30 AM ET. You can catch the live webcast of the call on the company's website.

For the quarter that included the package delivery service's ongoing dispute with the Teamsters and the expansion of services into Canada, analysts surveyed by Thomson Reuters expect the Memphis-based company to report earnings of $0.52 per share, down 64.1% from the same period of the previous year. Revenue for the quarter is expected to have fallen 15.4% to $8.4 billion.

Sometimes a seemingly small issue is transformed into a much larger problem. This is what happened between the U.S. and Mexico. The U.S. had a "pilot program" allowing Mexican trucks to cross the U.S. border and use U.S. roads. The program was halted last week on the grounds that the Mexican trucks were unsafe.

Mexico retaliated and said they would raise tariffs on $2.4 billion worth of U.S. exports. Mexico's tariffs would be increased on 90 industrial and agricultural products. These tariffs are set to be imposed later this week.

United Parcel Service Inc. (NYSE: UPS) plans to set up a pool of money that will be run by the Teamsters. The capital will become the new health fund for employees at the company. First, UPS will pull out of the Central States Pension Fund, which handles benefits for a number of trucking companies.

According to The Wall Street Journal (subscription required), "the move would shed an annual expense that reached $1.4 billion in 2006, up 14% from a year earlier." The plan is not unlike the one that General Motors Corp. (NYSE: GM) has negotiated with the UAW.

These deals are good for the companies, but are they good for the unions? They do often get job guarantees for their members as part of the contract. But, the new funds can lose value, and their ability to cover employee health care costs. Several years ago, a fund established for Caterpillar Inc. (NYSE: CAT) employees ran out of money.

Big labor may believe that it is doing a good job for it members who are in the workforce now. But, it may not be doing them any favors as they get older.

Twelve years ago the United States put the trucking provision of the North American Free Trade Agreement, or NAFTA, on hold.

In February of this year Transportation Secretary Mary Peters announced the U.S. will grant a maximum of 1,000 Mexican trucks access to U.S. highways for up to three years under a new pilot program. At the moment, Mexican trucking companies are allowed to transport goods within a 25-mile buffer zone from its borders into the United States. American trucks are currently not allowed into Mexico.

In the past three months there has been a great debate in Washington about what this trucking provision should allow and how much of an impact it would have on America's truck drivers.
