Pay them more!!!
Get rid of management and start over
More diversify within senior management will attract more diverse qualified candidates.
The ideals and values of the corporation do not always flow down to the working employee. That happens when management's personal objectives and ideas become the most important. Just treat people honestly and deal with them as valuable individuals.
Stop Nepotism and Cronyism. Reduce management levels back to only four.
Stop the lies and denial of being a great place. People are leaving because they are threating to new and more so with seasoned employees. Workplace bully managers who falsely accuse certain people of behavior issues and because they know how terrible they manage.
Pay market average salary. Not 15-20% less than average like they are doing now.
