I am working on a thesis that explores experimental ways to identifiy the relationships in a work enviroment and i need some background theory to base my research on.
Depending on your question about work relationships, you could begin by doing qualitative studies using grounded theory. You may find certain questions about work relationships, like productivity, have more studies done.
I did a doctoral thesis on An investigation of the knowledge base used by critical care nurses. I interviewed, observed and checked chart notes on 30 CC nurses in three hospitals. One of the findings was that nurses gravitated toward different types of interactions with patients, favoring two of them; physical, physiological, psychological and technical. There was agreement and disagreement about the value of these different aspects of care. One nurse, for example, who gave great physical care, on more than one occasion would do over the physical care of another nurse who she thought didn't do a good job. Depending on the work environment you are interested in, you may find some division in value of different aspects of a job.
In another qualitative study, I was asked to determine what makes good employees stay at their job in a hospital. This was a teaching hospital that was a beta site for testing of new equipment and procedures. That research kept employees working there if their department was involved. The departments that had no research or innovation going on, were losing staff. Women were happiest if the people in the work environment were collaborative and worked well together. Men did not mention that at all.
