to govern, to oversee, to manage, to direct official duty, office
軄 centers on the act of governing or overseeing: managing affairs, directing official duties, or holding an office. The meanings all relate to exercising authority in an organized role.
軄 is a rare character combining 身 (body, oneself) with 戠, which likely contributes the sound and relates to duty or office. The exact historical development is uncertain, but it appears to be a variant or older form of 職.
The left side 身 (body) suggests personal involvement, and the right side 戠 (which appears in 職, meaning job) hints at official work. Picture a person using their body to carry out official duties, governing and managing affairs.
For ショク, imagine a person in an office job (職, しょく) using their body (身) to oversee tasks: 職 -> ショク, and the body radical reinforces the personal duty.
