团体向政府争取的。

句子分析：Allowing domestic workers the freedom to seek the same type of work but with a different employer是动名词短语作主语，其中to seek the same type of work but with a different employer是不定式作定语修饰the freedom，谓语是is, 后面的what groups like Anti-Slavery International are campaigning the Government for是表语从句。if they so choose是条件状语从句，做插入语。

9. It is, they say, the right to change employers which distinguishes employment from slavery. (p9) 译：他们说，就是更换雇主的权利才能把雇佣同奴役区别开来。

句子分析：该句的主要形式是it is 引导的强调句。强调句子的主语the right to change employers. they say 是插入语。词组：distinguish A from B将A 同B区分开。
