This excerpt taken from the RIG 10-K filed Feb 26, 2009.
We require highly skilled personnel to operate our drilling units. As a result, we conduct extensive personnel recruiting, training and safety programs. At December 31, 2008, we had approximately 21,600 employees and we also utilized approximately 4,700 persons through contract labor providers. Some of our employees, most of whom work in Nigeria, the U.K., Egypt and Norway, are represented by collective bargaining agreements. In addition, some of our contracted labor work under collective bargaining agreements. Many of these represented individuals are working under agreements that are subject to ongoing salary negotiation in 2009. These negotiations could result in higher personnel expenses, other increased costs or increased operation restrictions. Additionally, the unions in the U.K. have sought an interpretation of the application of the Working Time Regulations to the offshore sector. The Employment Appeal Tribunal (the "Tribunal") has issued its decision in favor of the unions and held, in part, that offshore workers are entitled to another 14 days of annual leave. We have appealed in the first instance to the Tribunal. Oral arguments on the appeal have been held but no decision has been issued. The application of the Working Time Regulations to the offshore sector could result in higher labor costs and could undermine our ability to obtain a sufficient number of skilled workers in the U.K.
