Hmmm, just ask? Places that do timecards are probably more likely to say "yes". My employer allows it. Benefits other than health insurance (which is fully paid w/o any paycheck deduction) will be pro-rated to whatever you sign up for, but you can still work the extra hours for more pay. So for example if you promise 30 hours but work 36 hours, you'd get 75% benefits and 90% pay. If you promise 32 hours and work 50 hours, you'd get 80% benefits and 125% pay.
