In Switzerland the systematic surveillance of employees' monitors is NOT allowed by law. Only in exceptional cases it may be allowed (i.e. employee may think that there is some trade secrets revelaed, etc), but it is strictly regulated.
Your employer has no right
to check on your browsing habits, telephone calls, or read your emails. The penalty for this may be up to 3 years in prison.
"In contrast, the permanent individual-related surveillance of employees is forbidden by law in Switzerland (Article 26 Labour Regulation 3). The purpose of this prohibition is to protect employees from being exposed to a permanent, systematic surveillance of their behaviour. The surveillance of the screen, the keyboard and the mouse as well as so-called “spy programs”
violate the affected employee’s privacy and secrecy and are therefore not permitted. In addition, the employee’s privacy is protected by the Data Protection Act and by employment law."
