Good Company with Lots of Opportunity, but base salaries are lacking - Product Specialist bei Roche: Mitarbeiterbewertung

The company views promotions as a privilege vs. paying employees for the greater responsibility & more work that will be performed. The company cannot survive without their Specialists (product-specific experts) to help the Account Executives accomplish their jobs, as selling, contracting, negotiations, etc. are very complicated. And yet, Specialists make nominally more than Account Executives, even though they work harder & have much more responsibility. No wonder they have a hard time keeping Specialists & filling the vacant Specialist positions.
