Rapid antigen tests I do understand that, as none of the protocols are implemented, as yet as they warrant more in depth consultation.
But there are many companies, customers and suppliers now drawing the line in the sand, due to government mandates, and sending out letters that they do not want unvaccinated staff on their premises. This has a knock on effect as a PCBU may not other suitable alternative duties for the worker.

For small to medium business, this is not sustainable position, as many cannot afford to keep on staff that are not fulfilling their job description and doing the job they were hired for.
