Friendships can be complicated in the workplace, namely due to the fact  that both responsibility and obligation are involved with both fellow  employees and authority. Superficial and circumstantial interactions are  far more common in the workplace leading to a lesser chance of  developing lasting relationships. In my experience, many managers and  superiors discourage workplace friendships to protect productivity and  avoid distraction. It can also be difficult to relate to coworkers  outside of the work environment. People become awkward because the  framework in which they conduct the friendship is gone (p. 20). Also,  professional demeanor is often required at various jobs so this reaction  eventually becomes automatic for most of us. Each of us have personal  lives outside of work and may have bad days; however, we cannot allow  these situations to affect our productivity and must conceal certain  emotions or attitudes that can be toxic or unnecessary in a professional  setting. There have been experiences in my personal life where I  withheld feelings or feigned behavior in order to appease authority  figures or avoid complaints from disgruntled customers. I believe that  although this approach may be unethical in theory, it is necessary for  many if not all jobs because income and financial security are on the  line. I believe that a certain level of discretion is beneficial for  workplaces to run smoothly and efficiently, especially those within  customer service industries. In all, I agree with the sociological  consensus of distrusting or being cautious of the sincerity of work  colleagues.
