> success could get you promoted

"Could" is such a big word. It means nothing, but it is intended to be very valuable. Get that promotion in writing. Otherwise it's a carrot to dangle upon you.

> they'd better not send you on that expensive training course

You know what's worse than training people and then these people leaving? Not training them and then these people staying.

You insist on giving me reasons to stay away from that company.

Or it guarantees you’re in the next round of layoffs. You’re now a liability and they’ll be looking for a replacement with better loyalty signals.

You can wait for others to promote you as a carrot or you can promote yourself. With more power on the labor side, you can more easily promote yourself.

Big Tech started with a lot of power in labor due to the knowledge economy, and is losing a lot of their core power. Thus wages will start slipping more and more and converge to general market rate for talent. Reclaim that power!

> 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?
