13,000 HP employees worldwide work exclusively from home offices. In 2007 HP's teleworking program saved almost 2.5 million round trip commutes, saving approximately 65 million miles of road travel and almost 28,000 tonnes of CO2 emissions. This presentation will look at the implementation of flexible working practices within HP both in the UK and worldwide. It will examine the challenges which were encountered from both a technological and cultural perspective, look at the tools which HP employees use to communicate with each other, and explore the benefits that have accrued to the organisation.
