Slacking for dollars can also be considered giving yourself an invisible raise. It works this way: if you're being paid 10 dollars an hour but you feel you ought to be making 20 dollars an hour you only work for half of your scheduled time. So on a 8 hour shift 4 of those hours ought to be spent doing nothing. If you have a supervisor it's advisable to make your invisible raise look kosher by at least pretending to be busy.
