20 CFR § 604.4 - Application—ability to work.

(a) A State may consider an individual to be able to work during the week of unemployment claimed if the individual is able to work for all or a portion of the week claimed, provided any limitation on his or her ability to work does not constitute a withdrawal from the labor market.

(b) If an individual has previously demonstrated his or her ability to work and availability for work following the most recent separation from employment, the State may consider the individual able to work during the week of unemployment claimed despite the individual's illness or injury, unless the individual has refused an offer of suitable work due to such illness or injury.
