Why the use of ethical tactics in negotiation? and how does this impact your business?

I agree with you Syed.
Ethics is important in our life and in business.
it helps unite the goal of employer and the employees and it helps in steady growth of the organization.

Dear Ahmed, Companies should always stand and run on righteousness and must do things ethically.
The way a company negotiates with a customer or an employee tells a lot about the way a company is managed.
Simply put, negotiating ethically and a company will earn a loyal, trusting, and long-term repeat customer / employee and do it unethically, the company will have the customer leaving soon enough for someone he can trust and a disgruntled employee waiting to jump ships at the very first opportunity.
