I presume by W-2 they are referring to a local / state program and not the IRS document that working part of the nation is focused on right now, it being tax season and all. Please give us context by briefly describing W-2.
The Wisconsin Works program, more commonly known as W-2, was created by 1995 Wisconsin Act 289 to help participants achieve economic self-sufficiency through employment. It took effect statewide in September 1997. W-2 participants, who are primarily women with dependent children, earn wages or receive cash grants and other program services based on their employment status. Through September 2000, program costs—which are funded by state general purpose revenue and federal Temporary Assistance for Needy Families block grant funds—totaled $710.4 million.
Program participants receive services from counties, private agencies, and tribes under the terms of contracts signed with the Department of Workforce Development (DWD). W-2 participants are assigned to either subsidized or unsubsidized placements, based upon their level of preparedness for employment, and are eligible to receive program services that are intended to assist them in finding or retaining employment, increasing their skills or wages, and overcoming barriers to employment.
W2 is the 'Wisconsin Works' or 'welfare to work' welfare reform program.
