If I were In charge I would re-create a values statement that includes respecting the dignity and value of its people. I’d the senior people buy on others will! Do you know there are employees at Carefor who call others ‘fat’ and actually bully others! They are good workers so they get away with it. So, if I was in charge the hammer would come down.
Management needs to deal with the bullies and trouble makers. Instead of catering to them. Manage your people.
The only hope would be a complete rebuild.
Team building exercises, more autonomy, more dialogue between tiers.
