1--Johan hasn't turned up and Stefan is ill. Do we have anyone on stand-by?

2--I'm afraid not, we're very short-staffed at the moment. Can you ask the shift supervisor to ask one of his team to do some overtime? Perhaps Tommy can stand in for an hour or two until we find a replacement.

===================================

注解：

1.turned up出现

2.short-staffed人手短缺

3.supervisor监督人

===================================

译文：

1--约翰没来,斯特凡病了。我们有没有待命人员？

2--恐怕没有，我们此刻人手非常缺乏。你可以要求你值班主任给安排他的一个组加班吗？或许汤米可以替一两个小时班直到我们知道替班的。
