What is the ruling on working for a company that imposes corrupt conditions on its clients, such as a "bank guarantee letter" and "late payment penalty," and what is the ruling on the salary, incentives, and profits from this company? And does proof of the client's receipt of products fall under cooperating in sin and aggression, given the existence of bribes between some employees and clients that do not affect the receipts dealt with in the job?

If your work in the company is permissible and unrelated to prohibited matters, then there is no harm for you in the work, salary, or bonuses. The impermissibility of late payment penalties should be explained to those in charge. And if you know that one of the employees exceeds in charging the customer for something he was not instructed to charge, due to a bribe, then explain to him the impermissibility of his action and warn him against his deed.
