I am interested in privacy at the interface between one's personal and professional lives. This question is adjacent, but not identical to others related to IT system use (1, 2). Given a workplace IT system which is necessary to complete one's job duties, what rights, if any, do you retain as an employee to withhold your consent? For example, can you maintain that you do not personally consent/agree to be monitored even if your system states "by logging in... you acknowledge and consent to the monitoring of this system"? It seems unremarkable for an employer to ask for acknowledgement/compliance with system policies, but consent/agreement seems too much to demand. (Sub-question: by extension, could an employer require an employee to consent/agree to a physical search?)
I am specifically curious about law in the United States of America, but if there are relevant answers for other nations, those would be acceptable, too. Thank you.
