I believe he was saying he would not have accessed his email on his work computer at all, he would then log into Google for other reasons and not open his mail. But Google would then go ahead and show him something related to his email account that he did not want.
Leaving his computer logged into his Google account and his employer sitting down to go through the account, such as sent mail, is a different matter.
The solution to all this is to never use personal logins for anything on a computer you do not control 100%.
Yes exactly, thanks talmand for the clarification, i was thinking about the case in which the user is not logged in the mail but google fetches data for your search from all your personal data just because you're logged on.
