dating a colleague, or even being in a relationship with one , i believe , is not detrimental to the workings of the office, IF the priorities about work and leisure are clearly outlined in the minds of both people involved..it is expected, in a professional setup, that work comes first., and relationship issues do not interfere with productivity..of course this looks like an ideal situation-one that almost never does happen, but i think i can say with a fairly certain amount of confidence that it IS possible...
