(3) Nothing in subsection (1) (b) or
(2) (c) renders unlawful discrimination by a principal against a person on the
ground of the person's responsibilities as a carer if taking into account the
person's past training, qualifications and experience relevant to engagement
as a commission agent and, if the person is already engaged by the principal
as a commission agent, the person's performance as a commission agent, and all
other relevant factors that it is reasonable to take into account, the person
because of his or her responsibilities as a carer--
(a) would be unable to
carry out the inherent requirements of a commission agent, or
(b) would, in
order to carry out those requirements, require arrangements that are not
required by persons without those responsibilities as a carer and the making
of which would impose an unjustifiable hardship on the principal.
