Don't mind them whether you are required to work with him/her and act like the better person that you are. Don't try to bet this person or you will most likely be fired.
One of the best ways to deal with a stubborn wife is by expressing feelings calmly. Learning how to fight fair is also another way to deal with stubbornness.
Because the actual defintion of intractable is hard to control or deal with, and someone who is stubborn won't let you control them, and are hard to deal with. This is for Word Within the Word right? Ugg I hate it!
I think you tell it with your WHOLE body, what to do. Whenever it is stubborn, keep on doing that so the horse knows who's boss.
Make them an a deal they cant resist
Report it to your boss but tell the boss you want to remain anonymous.

Hiring that coworker
Resistant to authority, stubborn. Difficult to deal with. Usually refers to a person.
If they broke a policy, you need to give them a warning. If they break the policy again, you can fire them.
If the coworker is your boss or somehow superior to you in rank, then do not correct them in front of the visitor. I myself have gotten in trouble for doing that myself and have learned my lesson. If it is a coworker that has the same authority that you do, then unassertively suggest the correct answer. For example say, "Joe, I believe that it's...." or "Are you sure? I thought you had to...." If the coworker is still adamant in his or her information, don't push it because it would be unprofessional to bicker and fight in front of a customer/visitor. Either wait for that person to walk away and discuss it and maybe you can chase them down if its that important, or discuss it with your superior if you think the coworker is being stubborn about issues like this.
