Do you have a dog?
If so, you know that, above all else, dogs value … food, yes, but consistent behaviour from their owner. That is how you train your dog – by applying consistent behaviour tied to small rewards and giving praise when they do something you perceive as good. You make it clear how you want them to behave and reward them when they do so.
People are not very different.
If you make it clear to employees how you want them to behave and praise or reward them for good behaviour – and do so consistently – they will respond with their loyalty – and with their productivity.
