Normalizing a denormalized table representing employee information in a company database. The current table contains redundant data and violates normalization rules. Normalize this table up to the Third Normal Form $(3$NF$)$ by creating new tables and defining appropriate primary keys, foreign keys, and functional dependencies. Draw the ER diagram of the $3NF.$

Denormalized Employee Information Table:
