参考下面一段文字,CO的补料信中说essentially important最重要的是reference letters推荐信,其它的材料(合同、工资单、税单、代收代缴税务证明等)只起辅助作用,也就是说在evidencing work experience中,它们可提供可不提供,不是非常要紧,我的理解对吗?
Other documents which may assist in evidencing work experience claims could include, but are not limited to:
contracts
pay slips
tax returns
group certificates
