He want to say:

if you consider me as a Junior , you find me a Junior , That it means : Don't expect from me to perfect tasks of Senior .

And, if you consider me as an expert , you will find me an expert :

Is there a proverb means that ?

UPDATE:

the employer concentrate on experience .Indeed , he thought that "An expert is one who has worked for many years" . However ,It is not always so . you can find someone who has worked for a few years, but he is gifted .

It is not an issue of Salary , But It is a psychological issue that can negatively affect the performance of this gifted worker .

He expects an appreciation befitting his skills

Answer 1

This is an interesting issue on job motivation and expectations.

I think you could say that that your employer will get what he deserves by keeping expectations lows failing to motivate his employees. If he treats you and pays you as a Junior, he is probably likely to receive that standard of performance by you.

Answer 2

I'm not sure of how well an employer would take it, but the proverb 'You get what you pay for' conveys what I think it is you want to say:

In commercial transactions, the quality of goods and services increases as the prices increase, i.e., the more one pays, the better the merchandise.

Answer 3

Consider the idiomatic get/have what's coming to one.

what's coming to one: what one deserves.
