IF (big letters as I cannot underline or italicise) it does satisfy criteria stated in section 13 of the SCC, it would either be 13(d) medical examinations and/or 13 (m) medical aid.
When I look up 'medical' as a synonym, it does come up with 'health' as an alternative.
However, the synonyms for 'aid' it comes up with are "assistance, help, support, relief, encouragement, service, utility, benefit".
Consequently, you could construe that medical aid = health benefit and private health insurance would to be health benefit included in a employment package.
In addition, medical examinations could be included in a private health insurance, either on pro-active basis for a general health MOT or in response to a specific condition.
So having started off in the 'Probably not' camp when I initially looked at this question, I now would err more towards saying 'Yes'. Having said this, I would expect the cost of taking out the insurance to be at company level and therefore see evidence of the cost to the company divided by the number of its employees who have that benefit.
