Acme Packet® (NASDAQ:APKT), the leader in session delivery network solutions, today announced the Company has been named one of the Top Places to Work in Massachusetts in the 2011 employee-based survey project from The Boston Globe. The Top Places to Work 2011 magazine was published in the Sunday Globe on November 6. The Top Places to Work survey honors employers who care for their most valuable resource – the people who work for them. The employees of the winning companies reported that their employers pay well, offer progressive benefits and creative perks, allow the flexibility needed to have good lives at work and at home, embrace the diverse backgrounds of their employees and offer a promising future to all of their workers. The rankings were organized into three categories: Large, Midsize, and Small companies. Acme Packet was recognized in the midsize workplace group of 35 companies, defined as those with 250 to 999 employees. Acme Packet currently has 746 employees. The Boston Globe invited 1,076 employers to participate in the 2011 Top Places to Work. Of those, 237 organizations employing a total of nearly 200,000 people went all the way through the process, allowing The Boston Globe to conduct a confidential survey of their workers. Research partner WorkplaceDynamics contacted 121,000 employees and received completed surveys from 73,813 individuals. Each was asked to grade their organization’s performance according to 24 distinct statements, ranging from “New ideas are encouraged at this company,” to “It’s easy to tell my boss the truth.” “We are extremely proud to be named a Top Place to Work in Massachusetts by The Boston Globe,” said Andy Ory, Acme Packet President and Co-Founder. “We are committed to ensuring that our employees are completely informed of our common goals, strategies and results. We tackle challenges and opportunities as a team and encourage our very talented workforce to innovate and drive new processes to better serve our customers. It is gratifying to have our team validate why they like working at Acme Packet.” Earlier this year Acme Packet was ranked ninth on the “Globe 100” List of top-performing Massachusetts’ publicly traded companies.
