Anglo-Dutch oil company Shell has said it is considering the position of a number of workers as part of a long-running review of its operations.
Shell profits have been under pressure in recent quarters
The comments come after reports that the company was looking at offshoring as many as 3,600 posts in its information technology (IT) division.
Shell said it was in talks with firms over the possible move, and was also thinking about other changes.
It added that no decision had yet been made, though that would happen in 2008.
Shell has 108,000 staff worldwide, based in 130 countries.
Since 2005, the company has been reviewing its business in an attempt to cut costs by about £500m a year.
As well as the possible changes in the IT operations, Shell also said it was looking at reducing the number of staff at its finance division, as well as combining other departments and operational centres.
Shell is not alone in trying to cut costs, and rival BP also has announced plans to reduce overheads.
