For fuck's sake, Julia - this is a tired argument and not one that justifies further erosion of privacy and freedoms.
1. Untrained network and systems administrators do not guard against terrorism: authorities do.
2. Authorities who need access to data for a national security investigation are going to get it, regardless of employee consent.
3. Many workplaces make surveillance a condition of employment. There's little benefit in changing legislation just to make it easier for companies that have not yet informed staff of the intention to monitor usage.
4. The EFA is right: the powers will be used to serve the corporate agenda more than they will be used to protect national security. Are any safeguards going to be introduced with these changes?
