1. A considerable number of employees browse websites unrelated to work during working hours. These websites may be undesirable, such as entertainment, shopping, or pornographic sites. On one hand, they take up a large amount of working time; on the other hand, they cause harm to the mental health of employees.
2. A considerable number of employees use various chat tools, such as QQ, MSN, and Yahoo Messenger, for chatting. This not only takes up a large amount of working time but also these chat tools may unintentionally leak the company's business secrets.
3. A considerable number of employees play single-player or online games using company computers. These games not only take up an employee's time but may also lead to imitation by other employees, generate noise, or consume excessive company bandwidth, causing the company network to slow down, become congested, or even crash, resulting in important business information failing to be transmitted in time and causing business losses.
