Answer:
a. In this situation, I would approach the individual privately and ask if there are any technical difficulties preventing them from turning their camera on. If there are no technical difficulties, I would ask if there is any discomfort or any specific reason why they don't turn their camera on during meetings. It is important to approach this situation with empathy and to give the individual the opportunity to express any concerns they may have.
b. Requiring everyone to have their camera on for meetings may not be the best solution, as there could be various reasons why someone may not feel comfortable turning their camera on. However, it could be helpful to establish guidelines or expectations for meetings, such as encouraging participants to have their cameras on when possible or ensuring that everyone has the opportunity to speak and participate in the meeting regardless of whether their camera is on or off. Ultimately, the approach to cameras during meetings should be based on the needs and preferences of the team, and should be flexible to accommodate individual situations and concerns.
