Having a virtual office can cause employees to miss out on the social advantage of being in an office. Virtual employees can suffer from the "out of sight, out of mind" effect, in which they could be passed on for promotions or opportunities because they weren't in the office for management to consider them. They also can miss out on networking opportunities which could lead to other options in the company.
Employees who have virtual offices or telecommute work more hours than their office counterparts. People who work in a virtual office can often blur the difference between home life and work life. Unlike employees who can leave work at the office, employees with virtual offices tend to continue to work outside of "normal" work hours. According to a report from the Bureau of Labor and Statistics, 50% to 67% of telecommuting hours push the employee’s over 40 hours a week.4 Some reasons for these additional hours could be the employees’ desire to justify their telecommuting by being more productive and continuing to work beyond business hours or a result of companies maximizing their salaried employees by providing them with virtual offices to be able to continue work outside the office.
