There was a greater dispersion of the workforce this year, with many more working remotely, says Citrix.
A survey Citrix conducted among 160 IT decision makers at one of its remote working and app delivery management events found that 43% had seen wider employee distribution this year.
In addition, 58% expected a further employee dispersion increase in 2009.
The biggest driver for the increasingly dispersed workforce was cited as "employee demand", at 32%.
"It seems employees are seeking to reduce travel by working from home," said James Stevenson, area vice-president for UK, Ireland and South Africa at Citrix.
"However, with more and more people working away from the office, the pressure is on IT managers to deliver an optimised service to all on the network, no matter where they reside."
Stevenson said, "Historically, working away from the office is likened to being treated as a second class citizen - slow application delivery, little IT support and even total application failure. This cannot be the case in 2009."
