Your employer won't care. I've done this in my old mega-corp job (where between 401K and exec comp plan I had my take home at about $50/pay). I did it this year at my college gig - only issue is that I didn't have enough pay to pay faculty dues, so my school payroll had to do a manual adjustment (I simply explained I wanted a net $0 paycheck if possible).
