Explain three reasons why it is unwise to lie when negotiating.

The main reason that one should never lie on the negotiation table is that the person might not want to deal with you once he/she is likely to know about your lie and in the long run it is not good for the reputation of the company.

Secondly, with the help of lie one can make the other person to have deal with them but that the liar might not able to provide the other party with the required output as they promise while negotiating.

The third disadvantage of the lying is that while negotiation is that the deal might be cancel because in more of the cases where the one party lies the deal eventually cancels because the professional people are very good at detecting lies.
