Doesn't work if your bosses are clueless / nontechnical or powerless (or a combination of all of the above).

I've got hardworking coworkers that deserve a raise, and they won't since they won't negotiate and the boss (deservedly) doesn't have the political clout within the company to negotiate for us.

Edit: this at a largish company. Obviously doesn't apply to startups and smaller companies.

Do yourself a service and read Putt's Law then compare it to your own experience. You will notice that karma has nothing to do with anything at least in a material sense.

But better life experience might be a very possible.
