A cutthroat environment, characterized by intense competition and a focus on individual success over team success, can be harmful to productivity for several reasons.

First, it can lead to a lack of trust and collaboration among employees, which can impede the flow of information and ideas, and slow down the decision-making process. This can make it difficult for teams to work together effectively, which can lead to delays and missed deadlines.

Second, a cutthroat environment can also lead to high levels of stress and burnout among employees. This can reduce motivation and engagement, leading to lower productivity and increased turnover.

Third, it may also create an atmosphere of fear, where employees are afraid to take risks, make mistakes, or speak up with new ideas. This can stifle creativity and innovation, which are crucial for productivity.

Finally, it can also discourage teamwork and cooperation, and create a culture of backstabbing and sabotage, that can lead to low morale, lack of motivation and ultimately low productivity.

In summary, a cutthroat environment can be harmful to productivity because it can impede collaboration, lead to high levels of stress, reduce creativity and innovation and discourage teamwork and cooperation.
