There are rules and agreements with the Vaad that you are connected to. And don’t forget that if you don’t have a temidi you still have a yotzei v’nichnas who will realize that you are gone and you will lose your hechsher. If you know that you will be away for a period of time or you know that you are ill and will be out a day or two it is your responsibility to call the vaad and get a mashgiach temidi to fill in for you and yes PAY them. If you don’t the VAAD will consider you unreliable and either take away your hechsher or take away your keys and require that you have a full time temidi.
