We go over every single detail that we each took care of the week before and everything we're planning for the coming week.
That is great advice, but myself and the other tech are second-class citizens in terms of a lot of things [we don't have all the admin passwords, we can't join PCs to the domain, stuff like that]. Most of the stuff that she stresses about is stuff that only she is allowed to do.
Two points -- one, if there is a heavy workload, suggest shortening up the meeting so your whole team gets 5-ish man-hours of work time back per week. Two, ask if some of the onerus tasks be parsed out to individuals on the team. Having her have all the accesses is fine, but right now, she's a single point of failure for your entire team. Flip it over so that each one of you gets a task, she retains her rights since you will need a backup for the tasks but it moves her from being primary.
And having been just given a year-end review by someone who was my "manager" for five weeks and who has tried to fire me in the past, I understand the basis of having a terrible manager to deal with.
