There is some overlap in the use of the adjectives unsociable, unsocial, and antisocial, but they also have distinct core meanings. Generally speaking, unsociable means 'not enjoying the company of others', as in Terry was grumpy and unsociable. Antisocial means 'contrary to the laws and customs of a society', as in aggressive and antisocial behaviour. Unsocial is usually restricted to the sense ' (of hours) falling outside the normal working day', as in employees were expected to work unsocial hours.
