Is It OK To Be Emotional In The Workplace?

I guess the first thing to consider is what do we mean by 'emotional' and to what level can we express them. Stomping to the corner of the office and sobbing uncontrollably - possibly not. Or the recent case of the man in Liverpool who drove a digger into a newly-built hotel reception, causing extensive damage and possible harm to others - no. But we are human and certain elements of our psyche do not switch off just because we are at work. In fact, the workplace may emphasise the emotions we desperately try to hide.
