In dealing with contracts, one issue that sometimes comes up especially when working with a company that is overseas is pay of currency. Contracts were written the amount that they would be paid in US dollars, but sometimes the company would want it written in their currency, such as Euros or Yen. That was a minor discrepancy that occurred from time to time. As Chris mentioned about contractors, I have also dealt with contractors working at our site and any time you asked them to work over time or any number above the regular 40hrs a work week, a special work order form would have to filled out so they would be billed for the extra hours they were working.
