Any person determining whether a dismissal arising from ill health or injury is unfair should consider -
(a) whether or not the employee is capable of performing the work; and
(b) if the employee is not capable -
(i) the extent to which the employee is able to perform the work;
(ii) the extent to which the employee’s work circumstances might be adapted to accommodate disability, or, where this is not possible, the extent to which the employee’s duties might be adapted; and
(iii) the availability of any suitable alternative work.
