13. If my employer reduces my work hours, will I be eligible for UC benefits?
Where a claimant works less than his full-time hours through no fault of his own, the claimant may be potentially eligible to receive full or partial benefits, depending on his gross earnings and Partial Benefit Credit (PBC). A claimant’s PBC is the amount equal to 40 percent of his Weekly Benefit Rate (WBR). Where a claimant is working less than his full-time hours and his gross earnings for a week are equal to or less than the PBC, the claimant’s full WBR is payable for the week. When the claimant’s gross earnings for a week exceed the PBC, the gross earnings are deducted from the sum of the WBR plus PBC to determine the amount of any partial benefits for which the claimant may be eligible. NOTE: If the claimant’s gross earnings for a week are not a whole dollar amount, the earnings are rounded up to the next dollar.

If the claimant’s gross earnings for a week are equal to or greater than the sum of his WBR plus PBC, no benefits are payable for the week even though the claimant may have worked less than his full time hours. A claimant working his full time hours is not eligible for UC, regardless of the amount of earnings for the week.

The following examples illustrate how the amount of any partial benefits payable to a claimant who worked less than his full time, is calculated. In each example, the claimant was determined financially eligible for a WBR of $100. The PBC for each example is therefore $40 (40 percent of $100).

The question I have if they bring me back as a consultant for 24 hours per week for a project & at the completion of the project they let me go. Can I apply or reapply for unemployment?
