Does your manager and colleague know you have anxiety?

@Twyxz No. They know some other colleagues have autism and joke about that behind their backs. I don't want them to know.

@NathanCooper I just wanted to highlight that I am not clueless. Of course, I put two years on my CV and apply for jobs that require two years or less experience. Sure, I still have to learn a lot. Programming is an ever-changing field.

Is shouting in the workplace common in the Netherlands?

Possible duplicate of How can frequent anxiety attacks affect me in business and the workplace?

@jcm No, especially not in office-jobs. It happens in field-jobs sometimes, but is generally considered unprofessional unless required due to noise.

@jcm It is not.

Regarding your anxiety: I know from a number of people who thought that they are anxious (or who actually were anxious as a consequence), but in fact are/have one (or more) of {autistic (including Asperger's, who often go unrecognized), AD(H)D, introvert, child of narcissistic parent, ...}. It can also be a symptom of something else. I am not claiming this applies to you, but there are many free and quick screenings available online that should not be ignored because depending on were you live, physicians often build there conclusions too quickly ("In die Psycho-Ecke abschieben").

This developer you're working with is, unfortunately, extremely common. Those are the old timers that are afraid of new tech, the newbies that hide their incompetence behind arrogance, the superstars that thinks that it is their way or the highway. Those types are far too common, and learning how to deal with them is a valuable skill in the software world.

Just go search for a new job, if you have 1+ year work expierience as a developer you will find a new position within a month 100%

@ColinYoung I didn't mention it originally, so I updated the question. There wasn't any else within hearing distance when that happened, so it's his word against mine. Otherwise, good points.

Whatever you do, even if it gets much worse than now, don't quit unless you found another job. If you would really feel unable to work because of anxiety attacks, tell your boss that you are going home because you are not in a condition to work, and talk to your 'huisarts' or 'bedrijfsarts' on how to continue, on how and when you can return to work.

Surely if his knowledge is so outdated you can call him out on his methods that are no longer the industry standard then nudge the managers to retrain/get rid of him lol

I work in the netherlands too. Get away from there asap

Why are you using Linq to filter that list, a couple foreach work too the good news is, you are the better coder. So, whatever needs to be done, can be done from a position of actually being right.

@T. Sar. Hey, not all of us oldtimers are afraid of new tech. I've been doing this since the COBOL days. My 1st programming class was mainframe Fortran on punch cards. But yeah, there are some who can't/won't expand their skills.

Is your manager technical? That is, can he/she make independent assessments of your work?

@JimmyB I'm not saying that all oldtimers are bad! There are some oldtimers that are afraid of new tech, as there is some arrogant newbies, some insane managers and so on. It wasn't a generalization - I'm sorry if I wasn't clear!

(Don't know if this helps your anxiety, but) The good news is: Any good development department would choose you over your "write-foreach-since-20-years"-colleague without hesitation. You can find a new job easily. He can't. (I say that as an oldtimer who often has to interview people like your colleague...)

His behaviour sounds like bullying behavior. There are some good articles online for identifying and dealing with that behavior. I'm so sorry you have to put up with this.
