Reut Schwartz-Hebron, founder of the Key Change Institute -- an organization that focuses on workplace behavior -- believes that a constant state of positivity in the workplace can be "dangerous."
"There's certain things that have to be challenged," she said, "certain things that have to be improved you can't just constantly think that everything is going to be fine and positive."
Schwartz-Hebron -- a former Israeli military lieutenant -- said to improve working life, it is first necessary "to rewire your brain" by creating new experiences and engaging two different cerebral systems; the explicit and the implicit memory.
The explicit is responsible for storing information and facts while the implicit memory relies on previous experiences to perform a task and is associated with the subconscious.
"If you want to instigate behavioral change you need to engage the implicit system which operates in the subconscious realm," said Schwartz-Hebron, who runs workshops for Fortune 500 companies.
She added: "We typically work in very, very negative environments because our expertise is actually in difficult change."
"[The people we work with] don't see the need for the change; they don't feel the problem is being defined correctly or they don't believe that the solution is correct."
The study by the University of California concludes that while positive emotions are particularly important to encourage optimal success at work, it is important for employees and those in positions of leadership to experience both positive and negative feelings in day to day routine.
