Might this part of a contract refer to employee surveillance?

"We may collect a range of personal data including, but not limited to the followings: (...) Information about your use of our information and communications systems"

Could the above imply the employer can see what the employee is doing on their work laptop at all times?

Regardless, can a company legally spy on an employee without explicitly telling them so?
