Dear Ma'm,
I too had faced resistance when I wanted to collect data on employee satisfaction. We understand the target sector is service industry. Do you have any particular size of the firm, in mind ? Or would you consider a stretch of many companies within your sample size? Lets see how far we can resolve this.
