Companies have the option to provide different degrees of transparency to its workers that it believes will be appropriate to its circumstances.
For example, companies can limit transparency so that workers can only see their own equity, or only the equity of other people in pools they are a part of.
Companies can also choose to increase transparency by allowing them to see the equity of people beyond their equity pools.
Each company is different so there is no right or wrong answer as to how much transparency a company should provide. This will vary depending on the company’s culture, situation and circumstances.
