People should get to know each other more at work. Encourage breaks and building communities. We get involved in resolving disputes and we also do a lot in terms of employee relations and employee engagement.
It's always amazing how little people know about each other, even when they've worked in the same team for years. Lunchtime chatter is important too - in the UK we often skip lunch and work through - in many other more productive cultures lunch and discussions with colleagues is a key part of the day and is seen as far more important.
