There are different versions of a job guarantee---not all are universal.

A JG program is one in which government promises to make a job available to any qualifying individual who is ready and willing to work. Qualifications required of participants could include age range, gender, family status, family income, educational attainment, residency, and so on. The most general program would provide a universal JG in which government promises to provide a job to anyone legally entitled to work.
There are different versions of the JG. Harvey would provide a public sector job to anyone unable to find work, with the pay approximating a ‘market wage,’ whereby more highly skilled workers would receive higher pay.17 In Hyman Minsky’s proposal, developed further at The Center for Full Employment and Price Stability, University of Missouri-Kansas City, and independently at The Centre of Full Employment and Equity, University of Newcastle, Australia, the federal government provides funding for a job creation program that would offer a uniform hourly wage with a uniform package of benefits.18 The program could provide for part-time and seasonal work, as well as for other flexible working conditions as desired by the workers. The package of benefits could include health care, childcare, payment of social security taxes and usual vacations and sick leave. Congress or Parliament would set the wage, and the legislature would have to approve a rate increase – much as the minimum wage is currently legislated in the US.
