你可以叫那日本人跟老板講， The EEOC has stated that rules requiring employees to speak only English in the workplace violate the law unless the employer can show that they are justified by business necessity. A rule requiring employees to speak only English in the workplace at all times, including breaks and lunch time, will rarely be justified. 叫日本人，自己去google 一下！
我们公司有两个日本人，其他都是非日本人。某天他俩单独在讨论工作上的事直接用日语交流，没有其他人在旁边参与他们的谈话。abc经理（只会英语）找其中一个人谈话说，在公司不能说英语以外的其他语言，因为其他人只会英语。这是公司不成文的规定么？在公司和同事单独说话也不能说英语以外的语言吗？

あなたは何を言っていますか？

我根本就不会在乎，反正是人家俩之间的事，和我有啥关系
所以呢？
他们把不高兴写在脸上？还是找和你吐槽了？
他们不会吐槽，只会和VP说然后VP 会特别nice 的suggest 我们尽量说英语，VP不会说强制但是suggest是什么意思大家心里都有数。
哈哈哈还是杨超越说得对
