Shift the focus from individual achievements to team success. Establish shared goals that require everyone’s input, which builds a sense of unity and purpose.

Firstly, identify the root of the power struggle. From my experience they are the byproduct of: 1. Leadership Void: In the absence of leadership someone will try to establish roles and expectations. 2. Unclear Communication: If the message delivered is not the messaged received, the 'water-cooler talk' will create division. 3. Imposter Syndrome: Self-reflection, are you projecting or is it real? If you solve these collaboration and productivity take care of themselves.

1. Encourage open communication: Create a safe space for team members to share ideas, concerns, and feedback openly. 2. Clarify roles and responsibilities: Define clear roles and expectations to reduce ambiguity and prevent conflicts over authority. 3. Foster shared goals: Align everyone around common objectives to promote collaboration and minimize competition.

To address power struggles and foster collaboration: 1. Establish Clear Roles: Define each member’s responsibilities to minimize overlaps and conflicts. 2. Encourage Open Dialogue: Create a safe space for team members to share concerns and discuss issues constructively. 3. Promote Shared Goals: Emphasize collective objectives over individual ambitions to align efforts. 4. Model Collaboration: Demonstrate teamwork and cooperative behavior yourself to set the tone. 5. Recognize Team Efforts: Celebrate group achievements to reinforce a collaborative spirit.

Everyone needs an outlet for the extra effort they put in. Clear roles and responsibilities are needed, but this is a good problem to have as it means someone feels they are ready for more responsibility. Make sure your roles are clear, but steer the extra energy towards a shared goal that helps move the ball down the court for everyone
