Share-option plan and pension adviser

What are share-option plan and pension advisers and why shouldn’t boardmembers have close alignement with them?

A share-option plan is compensation for the employees in the form of company stock options.

Pension advisers are, well, advisers (maybe portfolio managers) for a company’s pension plan.

If boardmembers are aligned with advisers for either a share-option plan or a pension plan, they may be too strongly aligned with management, as management pays these advisers.
