Hi Cliff
Generally an employer has to
notify you before any surveillance of an employee is carried out in the workplace (this includes surveillance via CCTV, email monitoring etc). However, this is not a requirement in all states when it comes to email surveillance alone.
What state are you based in? Currently only NSW and the ACT have laws specifically dealing with monitoring of employee's emails by the employer. NSW, for example, would require that the employer give you 14 days' written notice that the surveillance is to occur and would also require that that surveillance be carried out in accordance with a workplace policy on surveillance. The only exception to this, would be where your employer has applied to a magistrate's court seeking an order to give authority for it to monitor employees without its knowledge. Practically, this can only occur where your employer is able to support suspicions that an unlawful activity is taking place.
If you aren't in the ACT or NSW then, arguably, your employer may not required to legally notify you of their surveillance of your emails.
Whether your employer's activities could come within the
Telecommunications (Interception and Access) Act 1979 (which is federal legislation and applies to all states), would depend on whether your emails/passwords are being monitored at the time they're "Passing over a telecommunications system" (as opposed to being monitored after they have been sent or received). As you can imagine, this could be quite a technical question to be able to determine. For your reference, the Act defines a communication as passing over a system when it is:
• sent or transmitted by the person sending the communication; and
• taken to continue to pass over the system until it becomes accessible to the intended recipient of the communication.
Do you have enough information about your employer's monitoring activities to determine the timing or point at which they might be accessing your emails?
