You're in a tough position, it sounds. You're a lead, yet likely restricted to leading technology and not so much people. I don't know what your leadership style is, but I've noticed some people are treated like bosses for merely acting the part, so that's something to consider.
Also, what I meant to say was that a person should skip standup if it actually benefits their productivity. They should show up to some standups, perhaps most. Hypothetically, standups could be done well, but I don't usually experience this. I don't think people should never show up to team rituals.
There must be an interesting story that explains why companies everywhere created the powerless tech lead position separate from manager. The tech lead is stuck in an impossible situation, apparently.
My team won't update ticket comments, they wont read emails, they won't read Teams channel questions directed at them. I try to keep these things at a minimum so that I can't be accused of making a point about over-stimulation - I get it.
But if they start to skip standup, the one time each day I can ask them where the hell one of my things I need is, then I have no reliable connection to them at all. And I'm not a boss so all I can do is beg.
