> The risk is that your snooping boss now thinks they'd better not send you on that expensive training course or assign you that big, important project where success could get you promoted. And that you'll never get a chance to address their fears, as they want to keep the snooping secret.

What a great reason to encourage employees at the margin to job hop! Better pay, negotiation of those expensive training courses and/or big important projects.

What's the downside here, exactly, to a more fluid labor supply/supplier's market?
