When I first started working for the school district

every new employee was offered a 500 dollar interest free loan to help defray the cost of not getting a paycheck right away. I took it and they took 100 dollars out of my paycheck every month for 5 months.
But, I guess it might depend upon other things such as job security and whether it would cause stress with the owner. In my case, there were thousands of employees so there was nothing personal at all there. And, it enabled me to pay my bills that first month.
