Rituals.
Might be a regular team meeting; or a pub / sports evening with colleagues. Might be a monthly 'em-ployee of the month' award. Something which binds the employee to the organisation - in a nice way, one hopes.
I spent some time in France and marvelled how a colleague or senior person would go round and shake hands with every colleague in the morning - almost a kind of respectful 'thank goodness we survived the night' daily event. I thought how poor the British are not to have that ritual - I still do think that.
