Yes, it is legal to fire employees in Hawaii for any lawful reason, including having too many tattoos, according to the “at-will” employment doctrine. However, the termination decision must be carefully considered in relation to anti-discrimination laws. Although employers in Hawaii may set dress codes and appearance standards that relate directly to the job at hand, if tattoos are connected to religious beliefs or cultural practices, terminating on this basis may be grounds for wrongful termination claims.
