“人蒸发啦？”市郊某厂，张三上早班。按照交接班制规定，早晨，他必须提前一刻钟到岗，与上夜班的李四面对面交接班并查验夜班操作记录，然后上岗。今天，他一反常规，既没提前到岗，也没查验记录，更没见到李四，而是迟到了半小时才上岗。上岗后“不问三七二十一”就抢时间? “People evaporate?” A factory in the suburbs, Zhangsan morning shift. In accordance with the provisions of the transfer system, in the morning, he must arrive one hour early, and face-to-face shift night shift and check the night shift operation records, and induction. Today, he is unconventional, neither in advance to post, nor test records, but did not see Lee S, but was late for half an hour before induction. After induction “do not ask thirty-seven twenty-one” grab the time?
