There's one thing that really fights akrasia, and that's being both observed and painfully accountable.

Akrasia typically acts via future discounting. Sure, it's worth doing, but it's not worth doing now; it can be done later. Having a boss who will yell at you (or fire you) if you miss a deadline or a supervisor who will chew you out for playing minesweeper takes away the future discounting problem, because the bad event is something that happens with high probability right now. There's nothing special about employment in this context; anything that makes the pain of procrastination immediate will fight akrasia effectively.

I'm just pointing out that taking employment as your example is overly narrow. There's a very clear mechanism (present infliction) by which employment fights akrasia, and it's how to use that mechanism that really deserves attention, in my opinion.
