Yii2 - how to structure the database correctly?

Question

Yii

Hello, please help with advice on how to correctly connect the tables according to logic?
1. There is a table - a list of offices (Head office and branches)
2. Table of departments. (The list of departments changes according to one or another office)
3. Table of departments. (The list changes according to one or another department)
4. Table of positions. (The list changes according to a particular department).
And there is a table of the workers themselves, where the relationship with all the tables above takes place. (Dismissal, appointment to another position, etc.). Can you please tell me how to store these links? Thanks in advance to all who respond.
