Masters Discussion Forum

Hi! Me and my friend were searching for potential master thesis topics. We have thought of a topic on how the employee satisfaction of a company affects its financial results/firm performance. We would like to examine whether there is a difference in between industries, based on their amount of human capital. 
​​​​​​​For this research we are looking for a database with data on the employee satisfaction of different companies (preferably within Europe, but not necessarily). We have not found this yet, so we hoped that someone here could help us with this. Thanks in advance for the help!
