Reporting by mail after reemployment

If a worker, except a partially unemployed worker, becomes employed in a week or immediately following a week for which the worker may be eligible for benefits and such employment prevents the worker from filing a continued claim, in accordance with regularly established continued claim filing procedure, the worker may claim such benefits by mailing to the office at which the worker registered for work and made the worker's claim for benefits, a report of such employment and all earnings received in such week, in the form of a signed statement which shall constitute the worker's claim for benefits for such week.
