When doing job, the most important thing is that we have to do the job effectively and completely in order to achieve the proper goal and result.  In workplace, we usually do our job with colleagues.  Therefore I think the most important quality of coworker  is cooperative attitude.

 

   Cooperative attitude toward other workers is essential for collaboration.  If we stick to our own idea and ignore others opinion, the job cannot be successful.  As I mentioned, we cannot do our jobs only for ourselves.  Especially as for big projects, workers proceed them with colleagues.  Therefore to do the job or pilot discussion for the project properly and peacefully, workers have to take other workers' opinions into consideration.   Moreover, meticulous preparation of each business plan based on thoroughly discussion will produce better ideas. 

 

  Disagreement during the discussion itself does not means uncooperative attitude.   Disagreement based on the opponents' deep analysis will make other workers different points of view and novel ideas about the business and deepen the discussion.  But we should consider the compromise plan according to the opinions so that all the workers agree with the whole direction.  Then after making the whole plan, they have to complete their respective job to do the job effectively.

 

 In this way, all the workers have to do their jobs properly.  Then, when collaborating, cooperative attitude is, I believe, the key character that make workers play their part in the projects well, keeping peaceful relationship with their colleagues.
