About 30-40 Lowe staffers are expected to follow Verizon Wireless’ creative account to sister IPG shop McCann-Erickson, sources said. McCann inherited the business after the client launched a review three weeks ago. About 65 Lowe staffers touched the business; sources said some of the remaining 25-35 employees will be laid off and some will be reassigned to other accounts or IPG shops. Lowe declined comment. Separately, the Bedminster, N.J., client last week hired Boston consultancy Pile and Co. to manage what is expected to be a fast-track review.
