Confidential
Information
The information of the company (be it e-mails, letters, manuals, agreements, contacts, etc.) is just that: It is the information of the Company and is not shared with anyone outside the Company or even in the Company if there is no business reason for it. Similarly, any information obtained from a Customer is not disclosed or shared outside of the Company and even then only with those within the Company to whom it pertains.
In short, employees are not permitted to disclose any Company trade secrets (commercial or otherwise), any confidential or personal information that they have been given access to in order for them to properly carry out their duties. This obligation extends to a fixed period of time after an employee leaves the Company as well.
