Should I say "to another" or "to another one"?

Question

What's the difference between these two expressions?

For example, I want to say

you can also assign a job to another
you can also assign a job to another one

Answer 1

Your both examples convey the same meaning and are grammatical.

You can also assign a job to another.

Here, another is used as a pronoun.

You can also assign a job to another one.

Here another is used as an adjective that modifies the pronoun one.
