Workers' Comp --> earned income --> EIC?

It does take the place of wages. That's the whole point of disability

I work at 'Storefront' and have a client whose husband has been
receiving "Temp Total Disability" paid through a "Workman's
Compensation Claims Account." He also received a lump sum for back
wages paid by Social Security in December, and Soc Sec is now paying
about $700 a month. Whether his disability is total is now being
disputed. However, be that as it may, he did receive this money, and
can either of these count as earned income toward Earned Income
Credit? Thanks.
