Warning sign 1) People aren't doing what they're supposed to, and rather than wanting to improve/rectify the situation, they don't care. Warning sign 1.5) Manager didn't consider this a problem. Warning sign 2) Manager burned you, the employee trying to do things right. Given my experience, at this point I'd leave. The department, or the organization, if I believed the problem went higher or would continue to haunt me. I've spent way too much time and energy making up for others willful deficiencies. Move one. Let them put themselves out of business.
