题型：判断题 阅读理解。 A good cell phone policy should be a required part of any company. It not only covers liability (法律责任) issues, but also covers many other legal and financial challenges that might cause you problems. For instance, there is an IRS guideline that requires company cell phones to be used only for business purposes. Personal use of these devices is considered as a taxable benefit, which can be considered as part of your income andtherefore must be included in the income to be declared for tax. Then how to make a good cell phone policy? Here are some tips for you to follow. Make sure there are provisions (条款) in your cell phone policy for business and personal use. You must make it clear what is allowed and what is not. A good Cell phone policy should clearly show your managers and employees the company-wide rules for cell phone usage. Thiswill avoid some managers making their own decisions. Employees should understand that cell phones are controlled not by them, but by a company authorized (公司批准的) employee who is the only person authorized to order devices, assign plans, manage devices and the like. This will prohibit employees from ordering whatever services they want. Another mobile device issue is liability for damage (赔偿责任). A good cell phone policy alsostates responsibility for lost or damaged phones and how to report problems. This will prevent confusion and help keep costs under control. Once you have a company cell phone policy in place, make sure you read and discuss itthoroughly with all of your employees. Have them sign the policy to ensure that they understandthe information contained within. Be sure to provide employees with a copy of the policy. Thiswill help reduce your company's liability for any legal issue that may arise.1.
