What is the ruling on working in a diaper factory as a computer and information networks maintenance employee, knowing that its transactions are permissible except for lending employees with a forbidden interest?

There is no objection to working in the aforementioned factory, as long as you do not directly engage in a forbidden act. Its ruling is similar to that of an owner of mixed wealth, with whom transactions are permissible except for the specific forbidden portion of the wealth. You are obligated to advise the factory owners and clarify to them the prohibition of usury. Working in a place free from such activities is better.
