I work at a large, international company, with my office situated in northwestern Europe, and my manager has recently asked me to create a safety poster for use at my workplace. He also included some images he wanted to be on it, but I am hesitant to use them because the company does not have a licence for their use (he's basically found them on the internet and assumed that they are free to use for anyone).
Since the poster only will be used locally the chance to get caught is next to nil, and when asking my manager about my concerns about infringements on the creator's intellectual property, my concerns were dismissed "since noone will ever notice anyway" and "everybody does it". I agree with both these points, but I am still disappointed in the company as I expected them to hold themselves to a higher moral standard - and that they'd be pretty paranoid of any potentially illegal business their employees engage in.
I am hesitant to push the issue, as my initial concerns were ignored. But; is there a point in bringing it up again after it was dismissed the first time, and what would be the best approach to get my manager to listen to me?
