Salary Scales Confidentiality

I work for HR for an international NGO who historically has never shared its salary scale with its staff. Justifiably staff feels cheated. I want to know what is the trend internationally about sharing salary scales with staff in international NGOs and other MNC's in general?
And does sharing scales bring out a lot of questions from staff?
Would appreicate guidance!

Salary scales are by and large confidential on most organizations, mate. Scales are by and large decided on "experience/competencies and role played". Compensation is as much about managing costs and expectations as paying as per scales. Simple reason, comparisons are endless and unless the scales are absolutely scientific ( am skeptical about it in the Indian scenarip, where overlaps are a norm) it is best to leave the document with the Compensation/Leadership team.

Who handles compensations of Directors, CEO, etc.? If it is finance department, then what about condientiality?
