According to "People's Republic of China (PRC) Labor Law" and "Regulations on Internal Management of Enterprises", employees should devote themselves to their work during their work, and should not engage in activities unrelated to their work, including playing mobile phones. Moreover, Jilin Hongtianyu Energy Co., Ltd. also has corresponding rules and regulations, which clearly stipulate that employees are not allowed to use mobile phones during work to ensure work efficiency and safety.
Using mobile phones during office hours will distract employees, affect work efficiency and quality, and even bring security risks.
