In prison systems, work release programs allow a prisoner who is sufficiently trusted or can be sufficiently monitored to leave confinement to continue working at their current place of employment, returning to prison when their shift is complete. The concept was introduced in Wisconsin in 1913 under the Huber Law program written by state senatorHenry Huber, which continues to be the casual name of Wisconsin's work release program presently .
Some work release programs allow greater freedom for the prisoner, allowing prisoners who follow a Monday-Friday work week to attend work and live at their homes on those days, and serve their sentences two days at a time on weekends. Depending on the terms of the program, the prisoner may serve their sentence in a halfway house or home confinement while not working. Other work release programs can be offered to prisoners who are nearing the end of their terms and looking for a reintegration into civilian life, with a possible offer of full-time employment once the prisoner is released.
