Emotions are an integral part of life. They are as important as logical thinking and a well-weighed approach to the decision-making process. Cognition and emotion have a strong relationship, as emotions are the result of the cognitive process. More complex concepts such as teamwork, decision-making, and organizational power/politics are based on emotions to a certain extent. Deep understanding of the cognition process that causes emotions can offer a better understanding of such concepts like power and approach in terms of organizational management. Considering the peculiarities of the chosen area, the paper aims at exploring such key concepts (and some of their sub-concepts) as cognition and emotion, teamwork, decision-making, and organizational power/politics change management, and trade unions, participation, and representation to evaluate cognition and emotion concepts in detail, and provide reflection regarding their practical use in daily life. Cognition and Emotion Cognition and emotion are interconnected. The following processes can be referred to cognition: language use, exploitation of memory, solving of various problems, focusing on something that draws attention, and planning. Emotions are the psychological states that may vary from happiness to depression, including disgust, anger, joy, and many others (de Sousa 2014; Hermans & de Houwer 2010). Heuristics and risk aversion are among the key methods determining the decision-making process. Heuristics The human mind tends to simplify problems to solve them to the extent suitable for its level of development. Heuristics are the methods of simplification aimed at achieving immediate results. These methods are often called ‘rules of thumb’. Heuristic methods or heuristics allow the human brain to pass the stage of complex and stressful calculations and come to the necessary conclusions, appropriate for the particular situation (Quartz 2009, p. 209). In other words, it is the process of determining the minimal necessary basis to make some decisions in the environment of uncertainty. The solutions made may not be optimal or the most effective. However, they allow resolving a situation with acceptable outcomes. People tend to assess situations assuming probabilities via their relation rather to the characteristics of events than to the events themselves (Quartz 2009, p. 210). In this light, heuristics are used to choose one solution from several possible alternatives. Risk Aversion Risks seem something unusual for the regular life of typical people. However, risks are an essential part of life, and people face them much more often than expected. Risk aversion is the concept that describes the particular choice of a person when the lower risks are preferred under the pressure of uncertainty. Such a situation is common for cautious gamblers preferring to choose lesser but guaranteed winnings rather than risk again to lose them all (Andersson et al. 2013, p. 10). Most people are risk aversive by nature, which can be a substantial obstacle on the road to success. It is one of the protective mechanisms making the emotion of fear of loss prevail over the emotion of excitement. Teamwork, Decision Making, and Organizational Power/Politics A work environment is the source of uncertainty as well as any othe
