While the idea is good, can you please elaborate on what exactly the company means by 'company values'? Please note that the definition could vary significantly from individual to individual and from company to company—fortunately or unfortunately.
Mutual Trust: A Foundation for Shared Values
First and foremost, for any two parties (be they individuals or companies/entities) to share something (values are on a much higher pedestal), there has to be 'mutual trust'. Does this exist between the employees and the company? If yes, your job is much easier. If not, you have a very tough task on your hands, as you first need to create mutual trust.
Management's Role in Understanding the Situation
Looking at your query from another angle, since you used the words 'Management is expecting', was any attempt made by the management or HR to find out the reasons for such a situation cropping up in the first place? Unless one knows the reasons, how can anyone suggest, let alone implement any suggestions? This brings us back to the point I mentioned above—MUTUAL TRUST. Unless this exists, any attempt to find the reasons would most likely hit a stone wall, meaning none of the employees would come out openly and transparently. I hope you get my point.
Understanding the Workforce: An Advantage
Regarding the fact you mentioned—"...60% of our staff members are not so educated...", actually, I think this is more of a blessing than a limitation. Somehow, education tends to stratify/harden the opinion-forming mechanism (mentally and emotionally) among people. The category of people who form a major chunk of your company would take time to get convinced/handled, but once convinced, they rarely change their stance/stand (unlike the educated lot)—basic human psychology, which our politicians use (or should we say, manipulate/exploit) to great advantage, if you have noticed. Another aspect of such a category is: they tend to think more often through the 'heart' than with the 'head' (which I guess is the prerogative of the educated). So, any idea that you wish to implement essentially and invariably has to consider this factor.
I hope I have not confused you further—do let me know.
