> You'll have to decide if prioritising the success of the company is more important than being nice
There's nothing to decide. OP said they are not in a position of power to fire those employees.
I've been in this situation and no amount of taking to founders helped. Maybe OP is in a different position but unless they were brought in to fix something urgent, I doubt the founders actually think there's a problem at all.
In my situation, I realized I was fighting up and down with people that didn't see the problem or didn't care so I just stopped. There's no point in trying to "fix" something nobody sees as a problem. Either you compromise your quality and get with the program or you just quit.
