I signed a contract - 36 hours for a certain amount of pay. I worked 36 hours the first week and they shorted me $300 dollars of my stipend saying i didn't start my contract till Tuesday so i wouldn't get my tax free money on my paycheck even though i worked 36 hours. Said that's what they do with all their nurses. All 4000. Add it up! Not onenurse t this facility is going to extend their contract- not because of the facility. 10 more weeks and i will be done.
