Open communication, building trust, managers who have the experience, managers that do more than just smile.
All of the gossip and drama would need to be address and fire those who are the root. Allow people to grow in the company that have the experience.
Clear communication, trainers need to be consistent and professional. Educate the management team and give them a better understanding of a quality management tea. Address all misconduct cases and fire employees not doing their jobs.
Not all departments of the company are treated equally. Getting a better leadership team would allow this company to grow. Providing the necessary tools to works to allow them to be successful. CEO shouldn't walk around and threaten peoples jobs for making mistakes.
