Employees should stay away from telling employers what type of equipment it should operate. Can you name a successful company, or even an industry, that has been successful when the employees dictate to the management and even the companies' founders what kind of equipment they can operate (i.e. scope clauses), what they will pay the employees to operate it, and when and how they will work (work rules)?? Can you name any?
If that is your desire, start your own business. Never outside of the airline industry have I heard employees who felt it was their right to run the company. If you are capable of running a business then do it. But when you seek employment at the door of another man, then let that man decide how and where to make the profits.
