4. Lack rapport If you cannot communicate freely and effectively with your boss or if you both cannot agree on any topics, it's almost clear that you both have totally different views as well as opposite personality traits. In such a scenario, your relationship with your boss will never flourish as you both tend to have opposite views on every aspect of your job. Rapport is considered to be the X- factor in any relationship when communication is effective between two people and both agree on similar decisions and judgments and get along very well, the opposite is the case when you lack rapport with your boss.
