The responding party employer sought reconsideration of a Board decision certifying the applicant union.
The employer argued it failed to file a response because the application package from the Board was missing the response form, and a Board clerk allegedly advised that returning the notice of posting was sufficient.
The Board dismissed the reconsideration request, finding the employer failed to exercise reasonable diligence.
The application notice clearly warned of the consequences of failing to file a response, and the employer should have contacted the Board for clarification rather than relying on incomplete information or a clerk's comments.
