Answer: True
Explanation: A workplace investigation can be conducted when there is information that may lead to significant misconduct, unethical behaviour or wrongdoing on the employees' part. As a result, organisations are allowed to monitor their company assets. This includes digital assets such as company laptops and cellphones.
Organisations are allowed to conduct covert investigations on these devcies, as long as they have stated this in a policy statement that has been communicated to employees. This statement gives them permission to monitor their company devices and if needed, conduct investigations (undercover or with the employee knowing) into possible transgressions without the need of a warrant.
