- in Washington, unused balances of 40 hours or less carry over from year to year, according to Washington State Department of Labor & Industries, so a year-end balance figure for each worker is the first number to record.
- in Washington, balances must be reinstated after a return to the same employer within 12 months, according to Washington State Department of Labor & Industries, so the separation date and the return date need to be recorded on the same line.
- in Washington, days worked before leaving count toward the 90-day period when a rehire happens within 12 months, according to Washington State Department of Labor & Industries, so the original start date stays on file alongside the rehire start date.
- in New Jersey, a change to the benefit year needs written notice at least 30 calendar days before the proposed change, according to New Jersey Department of Labor and Workforce Development, so the proposed change date becomes the starting point for the notice calendar.
Any other state's rule needs its own review before it is applied to a rehire.
