NO.PZ2016032802000014 问题如下 Sunny Raison, the rector of the researpartment, recently founone of his subornates, Tony, hsome violations on the report-writing. Then Sunny wrote email to warn Tony to stop violations right now anreportethese violations to his employer. Sunny violate the Co anStanr? A.No, because he warneTony to stop violations email. B.Yes. C.No, because he reportethese violations to his employer. B is correct.Accorng to StanrIV(Responsibilities of Supervisors, warning employee anReporting to employer are not enough for Sunny, he shoultake further steps to prevent more violations. 请问老师这里应该采取什么样的进一步措施呢，上报给公司让公司处理不属于进一步措施吗？那怎么样属于呢？
NO.PZ2016032802000014 前面老师有说要采取实际行动才不算违反CF那么难道发邮件警告和报告给employer不算实际行动么？那这算啥？？还是说理解为，发邮件警告和报告给employer都不能制止犯错的员工去停止犯错，必须采取某种手段当下立即阻止他犯错才行？
Yes. No, because he reportethese violations to his employer. B is correct. Accorng to StanrIV(Responsibilities of Supervisors, warning employee anReporting to employer are not enough for Sunny, he shoultake further steps to prevent more violations. 老师，如果上司通过邮件警告下属停止写报告，还不能制止下属，那应该采取什么样的措施呢
这题出的就不好，感觉说一半就没了，也没说后续是否采取行动，导致无法判断，容易歧义
如果采取了进一步行动预防，那么A C项写邮件和雇主报告是否是正确的，不违反准则？
