Henry Ford once said that too much friendship in the workplace is a bad thing. A few years ago, a Conference Board survey found that 87 percent of North Americans didn't like their jobs. Now, a more recent survey reveals that only 45 percent of Americans are satisfied with their jobs. A study conducted by Work Watch reveals that the workers who are satisfied with their jobs credit workplace friendships for making their job more fun.

Americans believe that workplace friendships possess more benefit than risk, that a more friendly workplace increases morale and open communication. It may also be difficult not to befriend coworkers as they spend so much time together at their jobs. But not all workplace friendships are created equal.

Some workers view workplace friendships as more of a risk because it creates gossip, favoritism, and can blur professional boundaries. A small percentage felt that it's wise to keep personal and professional lives separate, and they frown upon office romances.

When managers were asked their opinion on this, 49 percent felt that friendships in the workplace was a good thing while others viewed it as creating employee discomfort.

Nowadays the lines between personal and professional lives have been blurred due to the expanding roles that some people take on because of layoffs and hiring freezes.

All in all, I believe there should be clear boundaries in the workplace, keeping personal and professional lives separate.
