It could be genetic. RCCX gene mutations may make people more susceptible to CF/ME and being a software developer. For most people CF/ME will present as burnout.
It’s a proposed causation hence the ‘may’ qualifier. I’m suggesting people should check it out further. They may be surprised.
Also, it has huge implications beyond employment. My particular RCCX mutations yield hEDS which I can now treat. I wish I would have known 20 years ago. That’s one of many treatable genetic disorders that people barely know about.
It would also mean burnout is curable, so instead of not hiring people susceptible to burnout we can instead cure it for everyone.
