Mobile workers are using more devices to get their work done but there is still a high reliance on offices and desktop computers, according to research.

The global workforce study conducted by researcher TNS, and commissioned by Dell and Intel, suggests more than half of employees who work on a desktop PC also use another device.

Yet almost two thirds (62 per cent) of employees still consider the desktop PC as their primary business device for work, with the highest use in financial services, public healthcare and government.

"It’s essential employees have access to data when at the office, at home and on the road so they can stay productive, and IT secures and manages the data and user wherever it goes," said Steve Lalla, vice president and general manager of cloud client computing at Dell.

Ninety-seven per cent of employees spend at least some time in their employer’s office, with the average employee in developed markets spending 32 hours per week in the office.

Performance is the top device priority for employees, with 81 per cent stating it as either the first or second most important attribute.

The research surveyed almost 5,000 employees of small, medium and large organisations in 12 countries.
