这位仁兄,你的问题问得挺奇怪的。你是问当你被要求加班的时候得正在干什么,好奇怪。你应该问当你被要求加班的时候你会怎么做吧?
Nobody likes to work overtime, but there sometimes your company will need you to do so. First of all, as our traditional Chinese value, company or group's interest is the priority. Also, you will be paid more for working overtime, so the extra income is attractive to many of us. If we don't have anything originally booked after work, we should accept the requirement for working overtime. However,if we have appointments booked before we are noticed to work overtime, we should refuse the requirement because we need to keep our promises to other people as well.
没数字数,但应该差不多吧。
