Do you know how much income the investors/managers in your firm are taking home? How does it compare to your income? Are they factoring in your time and stress

Do you know how much income the investors/managers in your firm are taking home? How does it compare to your income? Are they factoring in your time and stress when making big strategic decisions? I've had coworkers that didn't pull their weight in non-union shops that were able to skate by because they were buddies with a manager who played political games well. My union (CWA) is pushing at multiple workplaces to have a more objective review and hiring process. But the occasional struggling or unprepared coworker has affected me way less than instances of poor management.
