【原文】
Another major factor to be considered is the cost of on-the-job training. Hiring outsiders allow a company to look for people who already have the particular skills and experience required for the job. The company will not have to spend time and money training an internal employee for the new job----something that has to be done when, for example, an employee is promoted from a technical position to a managerial one. In such a case, usually the employee would be sent to classes to help learn needed managerial skills.
【中文释义】
另外考虑到的一个重要因素是在职培训的费用。如果外部征聘的话，公司完全可以雇佣一个在相关领域有成熟技能和经验的人。相反，如果从内部提拔老员工的话，公司不得不重新花时间和精力来培训他。比如说，如果将公司的一名技术人员晋升为管理层人员，他必须要参加和管理相关的培训班。
【词汇注释】
major 主要的
factor 因素
particular 特别的，独有的，详细的
