'non-managerial' originates from the prefix 'non-' meaning 'not' and 'managerial' from 'manager,' which is derived from the Latin word 'manus,' meaning 'hand.'

'managerial' evolved from the French word 'managérial,' which was derived from 'manager,' and eventually became the modern English word 'managerial.'

Initially, 'managerial' meant 'pertaining to a manager,' and 'non-managerial' simply negates this meaning, indicating roles not involving management.
