Sorry to hear about that difficult situation! In situations where you believe that senior leadership knows about the problem and refuses to address it, you have three (3) options:
1. You can outline the problem and the consequences of that problem on the team/productivity in writing and send to 2-3 senior leaders. The documented and visible reporting of the problem would typically protect the reporter/complainant unless there's a lack of accountability.
2. You can find another job and workplace that is more supportive.
3. You can try to ignore the problematic management actions.
