How to Politely Address Salary Confidentiality in Employee Revision Letters?

When sending a salary revision letter to employees, is it correct to include a point like the one below in the email? Or how politely can we phrase this point? Can anyone help with this?

"Any discussion or disclosure of your compensation with anybody will be considered a breach of agreement by you."

Dear Anonymous,

Make it clear that any discussion or disclosure of your compensation with any colleague or anybody else will not be in good stead and might have an adverse influence on the performance of others. Therefore, you are advised not to discuss or disclose your compensation with anyone. You are required to treat this revised compensation as confidential. Any breach of confidential information will amount to a breach.

Thank you.

Yes, please add a point in the revision letter stating that "increment details are strictly private and confidential, must not be disclosed or discussed with others." Additionally, educate employees on how this could adversely impact them in general.

Transparency in Compensation Fixation

Considering transparency in compensation fixation is one of the most crucial aspects for any organization. Having said this, in order to avoid adverse effects, it is vital that the organization must have a good compensation policy that is open and can be revised based on performance, quality, and timescale. Any other increment in salary must have appropriate justification so that it motivates employees to give their best. Anything hidden today may be leaked and will have adverse effects. Best practices in company policies will always encourage employee retention and reduce attrition, leading to not just satisfied employees but also excited and energetic employees.

Has your company laid down such a policy and communicated it to the employees?
