<p><em>The purpose of this research </em><em>is </em><em>to explain influence</em><em> of</em><em> </em><em>conflict</em><em> management</em><em> strategy </em><em>on teamwork</em><em> performance</em><em>. This kind of</em><em> conflict can happen to everyone and</em><em> in any places disregarding</em><em> status, income and position. Someone who ca</em><em>n not</em><em> manage conflict</em><em>s</em><em> will </em><em>have a</em><em> threat</em><em> for his</em><em> personal performance</em><em>,</em><em> and </em><em>unfortunately, </em><em>company’s performance will </em><em>also gain</em><em> the effect. </em><em>Accordingly</em><em>, we need a strategy to manage conflict</em><em>s</em><em> as a</em><em>n</em><em> effort to create a good performance </em><em>for</em><em> individual employee performance a</em><em>s well as tha</em><em> team performance. </em><em>The p</em><em>opulation af this research is</em><em> the</em><em> entire educational employee</em><em>s</em><em> in UNNES by taking some samples using propotional sampling </em><em>to </em><em>around 88 samples</em><em>. </em><em>The result of this research prove</em><em>s</em><em> that hypothesis stat</em><em>ing</em><em> “conflict</em><em> management</em><em> strategy” influenced positively and significantly </em><em>on</em><em> </em><em>teamwork performance</em><em> is accepted. This</em><em> explain</em><em>s that </em><em>conflict</em><em> management</em><em> strategy can give contribution to</em><em> the</em><em> teamwork performance through employee’s </em><em>ability</em><em> to accomodate ideas from partner</em><em>s</em><em> of work, avoid </em><em>disputes</em><em> by respect</em><em>ing</em><em> each other, </em><em>maintaining</em><em> communicati</em><em>on</em><em> and </em><em>conduct</em><em> colaboration </em><em>on</em><em> work</em><em>ing</em><em> method</em><em>s</em><em>. </em><em>It is s</em><em>uggest</em><em>ed</em><em> </em><em>that</em><em> this research should improve strateg</em><em>ies</em><em> in managing conflict</em><em>s</em><em> such as strat</em><em>egies</em><em> to compete </em><em>at</em><em> work by giving chance to other partner to use theirs skill in making decision and finding solution to solve the job.</em></p><em>Keywords: conflict management strategy, teamwork’s performance, educational employee</em>
