Make no mistake about it; Company A WILL be notified that the employee has filed a claim, if Company A is in the base period, i.e., the employee worked there during any the first four of the last five completed quarters from the date the claim is filed. That means, if the employee files a claim in 4th quarter 2010, Company A will be notified if the employee had earnings in any quarter between 3rd quarter of 2009 and 2nd quarter of 2010.
