Because there is virtually no way adding a PE to a team doesn't add value unless you work in an exempt field. Adds value in marketing the company (e.g. +1 PE's on staff), optics to clients in correspondence, etc. If a company doesn't want to give you at least reimbursement for taking the exam and a modest one time bonus for time commitment in becoming a PE, I'd not advertise I was a PE on any client correspondence, marketing material, etc. That way if they saw no value in the PE, then I would be assured there wouldn't be any residual value earned from me. Then I would find a job that needed that value to gain additional compensation.
