Cisco

When technology giant Cisco promoted Chuck Robbins to the CEO post earlier this year, the move wasn't a quiet celebration confined to the C-suite. The company of 70,000-some employees across the globe came together and partied. Cisco held what it called "Cisco Rocks!" events around the world, beginning with a July 27 concert for 30,000 employees and their guests in Silicon Valley with performances from stars Christina Aguilera and Keith Urban. Then, over the next four days, Cisco threw 46 more parties in locations ranging from Boxborough, Massachusetts, to Bangalore, to Beijing. Employees dig the inclusive, exuberant culture. Said one after the Cisco Rocks! event in San Jose: "Beyond EPIC @cisco day today. #NewCEO & new day for an amazing place to work! Thanks for the fun!"
