Many employers choose to monitor, restrict, or regulate their employees Internet usage, and they are generally legally allowed to do so. The risks involved in allowing employees unrestricted access to the Internet often cause companies to adopt rules to protect their interests. Employees using the Internet at work may cause company computers to be at risk for computer viruses or hacking programs. Because of this, data loss or data theft is of great concern to many employers. Employers may also decide to restrict their employees Internet usage in order to increase productivity. Workers who spend a large part of their day using the Internet for personal tasks waste time that should be spent on work, causing businesses to lose money. Some employers may use tracking programs to monitor their employees Internet usage, therefore employees should not assume that what they do on company computers is necessarily private. Employers are generally within their rights to monitor their employees computer use, according to recent legal rulings.
