Do You Share Financial Data with Your Staff?

How much should staff members know about a firm’s financial status? Does openness boost morale and productivity or cause confusion and resentment? I’ve read some articles saying how sharing financial data with your staff allows them to understand the larger reality of the business—not me. I believe in showing staff their numbers against the others during evaluations. I believe in making staff understand how much pays their wage and how much they need to sell to make money for the company. But I don’t believe in them knowing my total monthly and yearly numbers. What do you think? And if you do share financial data is it with all staff members…or only managers? If you do share—has it really helped? Have you shared and it hurt the business instead of helping?
