AS A Manager : How do you keep relations with a person in cases where you cannot agree upon certain issues?

No two individual brains will agree to one thing specially when they are independent , strong and driven by motives hence one should try to access the things from other's perspective and understand this will help you to know the reason behind such view-point. The best way is to put your thoughts across .

Be honest with the person .. tell them what your point of view and concerns are ...

If it is ethical ... usually the other person backs off, since ethics are highly valued in business ..

I been told "you can not loose your job if you follow the rules and make a mistake, however if you act not ethical .. you can clear your desk now"

In other words .. a mistake usually will not get you fired, however if you conduct your self unethical that will get you fired on the spot 

Personal relations should be kept away. No ego problems in official matters. Two should sit together and the basis of merits which are beneficial a combined decision to be taken. Hence no question of disagreement.

Dear Mr. Emad

It is very natural and common phenomena that people are disagree on lots of issues but If as a manager if you observer there are even more issue on that both party are agree because both party work for common goal that is organization. Aside issues on which there is conflict there will be a mid may (manager have to find that) .

This will enlighten positivity in the organization relation.

Warm Regards

most of time clashes are "Personal" not professional. One should try to agree on "Common interest' in favour of the company.

Agree with answer given by Mr.Mohammed Asim Nehal

As a Manager, one comes across situations when he can have differences with person(s) specially when in pursuit of compressed timelines of technical projects. how to handle each situation would largely depend on the individual's position with reference to yours. if he is a subordinate, the manager should endeavor to persuade with logical reasons and later use his authority to keep the guy inline even if he's not agreed to manager's views and if you come across your superiors with different views then you are obligated to explain ur position if it is in the best interest of the organization..if ur point of view is not upheld, go with company policy until its legal..various organizations adopt conflict resolution procedures involving different methodologies so in short differences must be kept lower than the objectives value...

As rightly pointed out by Mr. Mohammed Asim that no two individual thinks alike, so it is quite natural. we have to adjust with circumstances and understand what actually was differing and try to find out a amicable solution for the difference and get along then as formal relation if not possible to maintain very friendly relations, as we live in a society had to maintain the relationship.. Thanks.

Make him understand what makes your opinion/position different from that of his/her and put all possible effort to bridge the gap within the professional framework.

If the proper understanding and mutual respect are there then relationship will follow.

Any sort of relationship without these two ( respect and understanding) is meaningless and certainly not going to help anyone professionally.
