听力原文： All employees are required to wear an identification badge at all times. Lost badges must be reported immediately to your supervisor. A replacement badge will be requested for you, and a temporary badge will be issued for the interim. In cases of repeated badge loss, a replacement fee may be charged at the discretion of the security office. Please remember that all visitors must be accompanied at all times by employees with identification badges. Visitors without escorts will be asked by security personnel to leave the building. Help us enforce this security standard by reporting any unescorted persons to the security office. Thank you for your cooperation. What should employees do if a badge is lost?
