The only relevant things in the job market are competency, and the ability to get along with co-workers and customers.
Can you do the job? Perform the task efficiently and competently? Can you overlook your co-worker's obnoxious attitude and carry on with your job? Can you respect the customer's humanity, desire sincerely to help him, and ignore their body odor? Do you refrain from being obnoxious and irritating yourself? Are you kind when people approach you with their concerns? In other words, if you can do the job well, and are not a lizard person, then you'll be successful in the job market, and in the other areas of your life. Why? Because in the job market, competency and tolerance of others are paramount.
BUT, tolerating others is not always easy. Some are straight-up bullies at work, some are loud and annoying, others are confused as to why they are there. Also, anyone who works in retail or in restaurants/bars etc., knows how rude and intemperate some customers can be. There are many good ways to deal with this, but perhaps the most important is that you do not devalue nor demean yourself-not even the Karen attacking you-and silently ask God to bless this person. I've tried it, and it helped to keep me in my center. Remember: you are capable of acting in the exact same way as a rude customer. DO NOT GET OFFENDED, ANGERED, NOR INTEMPERATE YOURSELF. "God, please help me to understand this person and help him in accordance with compassion, empathy and respect".Work can be fun, and almost always is rewarding. The point is, you really have no alternative. You either work, steal, or live off of someone else's work. Not only that, but you're going to be working about third of your life. Make it worthwhile! Know what you are doing and why, and love others as you love yourself.
