I know this isnt everyone that acts like this, but as a longtimer, this is how i see many in IT act in these roles:
I7: Works hard, gets told you have to do your tasks plus I8 tasks to be considered doing a good job
I8: Does the I7 work, all the I8 work and 95% of the I9 work
I9: Doesnt pay attention in teams calls, rarely knows whats going on in general and asks the I8 all the questions for the trivial things they do work on that they should know the answers to
Am i missing anything?
