employ, hire
雇 centers on bringing someone into service: employing or hiring a person to do work.
雇 combines 户 (door) with 隹 (bird). The historical connection to employment is uncertain; one possibility is that it originally referred to a bird kept at home, later extended to hired workers.
A bird (隹) inside a door (户) suggests a hired worker who comes inside to help: 雇 means employ or hire.
For コ, imagine a company hiring a new employee and giving them a small 子 (こ, child) to train: 子 -> コ, and the new hire learns the job.
