I've not heard of this before, so I'm trying to find out if an employer can legally enforce this. My company is planning to force employees to use their personal emails as their corporate accounts. Besides this being a bad idea from an IT standpoint, I'm not sure it is legal. The plan at the moment is to simply re-route company emails to the personal email account on file with HR. No permission of the employee is being sought.
As much as you hear about company's rights to personal emails sent from work email addresses, I can not even begin to fathom the can of worms this policy will open.
Any input would be welcome.
