“Rachit reports to Irina.”
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.
Rachit reports to Irina.
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.
