People don't appeal to each other
It can become a problem if there is no common corporate culture and no common communication 'rules'. The result is that there will be a lot of communication, but not the right and most effective solutions. If there is no common corporate culture in the company, this leads to a lot of discussion and misunderstandings.
It is therefore important that a company has an atmosphere of cooperation in which there is clarity about rules and agreements and in which employees can address each other in a safe manner.
