Most companies have line managers. Line managers are not directors, they are managers. There are also senior managers. I think your schedule is good but I think you should add at least 1 layer maybe two.

Yeah, I just ran out of employees to cover and I worked backwards, so I didn’t get to use the term manager. I guess the system is good until the 1.000.000 mark ;)

I think line manager is a generic term for the person you explicitly report to though (e.g. the one who approves your time off), not a role in specific.

You can have higher ratios at the CXO and SVP level, and need lower ratios below director because at the higher level most people dont need as much day to day oversight.

From my experience at the bottom, it’s the higher level people that need more oversight.
