Royal Dutch Shell has publicly announced it will slash 5,000 jobs by year end—including "hundreds" in Houston—as part of a sweeping reorganization new CEO Peter Voser said is needed to make the company more competitive.

But under a separate program, the European oil giant has been quietly transferring additional office jobs from Houston and elsewhere to India and the Philippines to reduce costs, according to internal Shell documents obtained by the Chronicle and a person familiar with the plan.
