I fancy that most people would prefer it if their boss didn't know what they're really like.
Work is work. And life is, generally, better than that.
Increasingly, though, employers seem to believe that they own you. Recessions have tended to help this notion, with many workers cowering just to keep a job.
Please imagine, though, the pained feelings of a fired Air New Zealand cabin crew member who was ordered by her former bosses to show them her Facebook page. Oh, and her bank records.
