Titles, such as professor and employee, refer to the employer. If you have work experience, write who the employer is and the relationship, that is, the relationship with you. If you are a tutor, you should write supervisor, and so on. For example, the relationship with dad, you should write about dad.

Matters needing attention
The signature position of the recommender is very particular. Generally, the signature is between the signature at the end of the text and the electronic name.
For example:
Sincere greetings!
(here is the signature)
John
associate professor
There will be a misunderstanding here. When three letters of recommendation happen to coincide, the structure of "signature:" is rarely used. Try not to use this "fill in the blanks" signature method.
Generally speaking, a recommendation letter needs three signatures: one on the recommendation letter, one on the recommendation form and one on the envelope, and then sign the date on the recommendation form. If authorized by the professor, you can sign the professor yourself.
