I don not think it a good decision that he be given this job

准确来说 举行有一点问题

你的意思是说 我不认为让他得到这个工作是一个好的决定。 吗？

如果是这个意思的话 试试我给你的建议：
I do not think that it is a good decision that let him do this job.

没有，要不就是你写错了…

有think...that...这个句型. 但句子毛病不少

这里有几处错误
可以这样表达：
I don't think it's a good decision for him to give up this job.

有问题
