To understand how business is communicating in the midst of these changes, Plantronics surveyed 1,800 enterprise employees in the US, UK, Germany, China, India and Australia. All work in medium or large size companies (100+ employees) and identified themselves as knowledge workers (people whose work centers on developing/working primarily with ideas and information) who use a variety of communications technologies to stay in touch with colleagues, partners and clients. The research was conducted in May and June of 2010.
