Some companies have option #2, a technical ladder for non-managers, where the managerial ladder is strictly superior in terms of informal social status and compensation. A few very advanced companies may offer #3 or something like it.
To the extent they do, we see another case of two ladders, but this time with a very obvious reason, much less a mystery than the officer/​enlisted or exec/​manager distinction.
