“Eugenia reports to the Credit Manager.”
There's an new employee in your department. You're introducing her to some of the people in your company. Now you're introducing someone who works for a person who she's already met.
Eugenia reports to the Credit Manager.
You can explain who a person's boss is using the phrae "__ reports to __".
If your boss is named "Jay", then you can say:
I report to Jay.
The reverse of this is to "have people reporting to" someone:
She has six people reporting to her now.
This phrase is commonly used in professional jobs and office jobs. It sounds very respectable.
Another expression for this is "works under ___":
Do you still work under Dharmesh?
In other situations (like at smaller businesses or service jobs), you can say that a person "works for" someone:
I work for Marcus.
And that person is the other person's "boss" or "manager":
Marcus is my direct manager, and his boss is the owner.
