Interview questions only to workers and sample only less than 10 workers. i hope that you can come out the interview questions ASAP which relate to this points:
Satisfactions Level (Rewards, Punishment, Working Environment)
Performances (Effectiveness, Efficiency, Productivity)
Management Skills (Leadership, Interpersonal Skill, Task Identify,Task Significance)
Bear in mind this is not a survey form but it is direct interview questions so that we able to recognize/identify the problem based on our own understanding with respond from the workers without using SPSS.
