Why treating employees well makes good sense

Treating employees well is beneficial to the organization itself as you get what you give and if the employees are treated well and with respect, they will do the same for the organization, they will work more effectively and efficiently in order to get the organizational goal accomplished. if the employees aren't treated well thewy might not be motivated to do the work and they might make more mistakes and can tend to work carelessly which can result to heavy loss to an organization which no organization wants.
employees those are treated well in an organization tend to give better performance at work they are much more motivated towards the organization's goal and objectives. So, if an organization want its employees to stay motivated and loyal towards the organization they should treat their employees with respect and should value them as eventually, they are the one who will get the benefit.
