I've been reading a report (issued today )(called when worker works)( produced jointly )by three organisations.
首先我的分断是否正确,其次帮我翻译下...不胜感激
答：首先将你的句子还原：
I've been reading a report issued today called When Work Works,produced jointly by 3 organizations.
你打错了一单词work不是worker,少了一个逗号.
然后再来句法分析：
主语:I
谓语：have been reading
宾语：a report
定语1:issued today
定语2：called When Work Works
这两个定语修饰 a report的
非限制性定语：produced jointly by 3 organizations.修饰When Work Works
译：我在看一份今天出版的名叫《当工作有效时》的报告,是由三个组织联合撰写的.
