L3Harris reviews

Under resourced, poor senior management, inadequate business models

Chances of getting a raise/promotion really depends on how much your manager cares/likes you and not necessarily based on your skill and contribution to the company. It varies. Best way to get a raise is to get an offer somewhere else and have them counter. Sometimes you may go above and beyond the call of duty for months, and all you’ll get is a gift card. I believe that having a clearance will afford you some extra favorability—they usually approve more vacation hours (200 hours easily, and more if it gets approved), and promotions seem easier to attain because they want to keep you after spending so much money on security clearances.
