There are many hechsherim out there, some are given the status of ‘not reliable’ by non-partisan kashrus oversight agencies. Generally speaking, would it be permissible for a shomer mitzvos Jew who needs an income to work for such a hechsher, knowing that he himself would not eat from the products they endorse?
Answer:
Many people work for hechsheirim that they themselves don’t eat, such as people who work for the Rabbanut and so on.
The fact that a person accepts stringencies for himself doesn’t mean that he can’t provide others with food that don’t meet those standards.
However, the condition is that the food should be kosher, at least on the most basic level of halachic observance.
Best wishes.
