116 - 你见过哪些员工因为作死被开除的事情？ - getting-fired.txt.txt

匿名用户：

老爹以前是某央企下的食用油生产基地的董事长，有天回来跟我说，他们的配电室被人扔了一颗炸弹。。。。。这个配电室可不是办公室的配电室，而是仓库的配电室，旁边全部都是油罐，如果发生了连环爆炸，后果将不堪设想。幸亏炸弹是有人自己用易拉罐制造的，威力不大才没有出大问题，只是暂时断了电。事发后配合警方各种追查，摄像头遭到破坏，不过通过绑易拉罐炸弹的透明胶带上的指纹，把目标锁定在了公司的某个刚入职半年的员工身上。小哥是工厂的加工员，刚入职半年。提审他的时候，他供认不讳。他表示他刚入职半年，从学校出来比较懒散，不适应公司的工作节奏。于是他做了个自制炸弹，趁没人的时候扔到配电箱里，想着只要公司发生了事故，他就能放假休息几天了。
