Once a week is too much too. Every other day is just strange. Where are you guys at and what are you zooming for?!
Letting your Managers boss know in whatever way is a good move. Maybe they will start reaching out to reps as a check in. That would be an easy opportunity to express the concerns of the team. Believe me, managers can and do get let go for creating a toxic environment. It has to be handled appropriately though.
The reality is some managers don't have the skillset or mental capacity to lead especially in a pandemic. 2 things are happening. First, they get nervous and feel the need to justify their jobs so they "Zoom." Second, SOME of them only know how to eat, sleep, and breathe sales numbers. They have a hard time leading in other ways.
IMO, the better question is what is the topic and is it beneficial to the team. If he or she isn't asking the team if its useful, then you have a bad manager. Period.
Here is the other problem. When reps are asked to meet and/or zoom, even for an hour, you must realize that you are essentially killing a half day minimum. Lets face it, some will take the whole day off. Probably why I don't see it much in my area.
How about taking the extra time to volunteer as a team and/or individually. What a perfect way to shine and give back in these times. That was a good suggestion.
