So far, based on the tone of your texts, I believe it. I don't know how you think it's impossible to have 12 NCNSs I've seen that level of NCNSs a lot in the PT inside ranks. If you think expecting people to come to work is a problem, you have an interesting take on the world.
The point of my post, which you seemed to miss, was that I would go through the attendance with my shop steward each day. If discipline for attendance came up, the steward would have seen the same thing I did. It's a lot easier working with the steward on those issues, the elected steward is usually your strongest sphere of influence.
Not all management were taught to work with their stewards the way I was, but I was lucky enough to have wise mentors.
