How do you properly say "reference check" or "employment verification" in Mandarin? I noticed that when I say I need to do a 背景调查, people get scared and tend to cut the conversation off. So what I normally say is 我要核查您以前工作人员的工作信息. I sometimes substitute "工作人员" to the actual job title of the person, eg. 会计. I believe I'm saying it incorrectly because although some people do understand what I mean, others still ask me what I'm talking about. I'm hoping that somebody here can help me out. Thank you in advance!
