Answer:
a. In the case of a participant who never has their camera on during meetings, it may be useful to have a private conversation with them to discuss the situation and to find out the reasons behind their behavior. It is important to be non-confrontational and to give the person the opportunity to explain their actions. It may also be helpful to remind them of the importance of active participation during meetings and to ask for their ideas on how to improve their engagement.
b. Requiring everyone to have their camera on during meetings can be a good way to promote engagement and participation. However, it is important to consider the reasons why someone may not have their camera on, such as privacy concerns or technical issues. It may be helpful to offer alternatives, such as the option to call in or to use a virtual background, to ensure that everyone can participate comfortably. It is also important to communicate the expectations clearly and to ensure that everyone understands the reasons behind the requirement.
