Bank of America is closing a regional office in Glendale at the end of the month with the potential for more than 100 layoffs. Employees at the 611 N. Brand Blvd. office were told in August the site was closing. Two hundred eighty one workers were notified they would be laid off, according to a Worker Adjustment and Retraining Notification filed with the state Employment Development Department on Nov. 14. But 100 of those employees had already taken other positions with the bank when the notice was sent, according to Rick Simon, a spokesman for the Charlotte, N.C.-based financial institution. “We continue to encourage qualified associates to apply for open positions within the company,” said Simon, in a prepared statement. Many of the employees in the Glendale office assisted mortgage customers who were delinquent on payments.
