I was also under the impression that EDS staff weren't paid as quite as much as their counterparts in other companies.
Although how anyone know that is a mystery a I'm told EDS staff are not allowed to talk about their saleries and could face dismissal if they do.
Both are a myth.
Lower salaries might have been an issue in the past but EDS have long since got fed up with staff being poached that were probably now slightly ahead of the competition. In fact, all offers by other companies for me to work for them have all been at a lower salary!
Salary discussion is a part of the Performance Appraisal process and it's actively encouraged to know what those around you are rewarded for the work they do.
However, EDS in America are effectively a TOTALLY different company - US workers are protected in the same way UK workers aren't and the work ethos is totally different. Same with EDS in India.
