Typical main content for employee survey is questions asking respondent opinion using degree of agreement format (strongly disagree to strongly agree) towards set of attributes. The number of attributes can be around 40-50 and attributes of similar aspects (teamwork, pay & benefit, communication etc) are grouped to make it easy for respondents to fill out. Ideally the attributes are the result from focus group discussion to ascertain relevancy. The survey result will identify company performance in those attributes.
