for promotion.

I'm korean.

T don't know what this sentence means.

I'd like to know,,

Answer 1

It means:only certain young employees
will be promoted.

There are restrictions and conditions in this promotion.

Answer 2

It means that to be promoted, candidates must have served a certain length of time. As most of the women in this post have not been employed there very long, they are not on the whole eligible for promotion.

Because the girls in this job are new, they will have to wait until they can be made into bosses.
