In tech there are many incredibly high paying jobs - taking control over your situation has a low bar.
if you don’t like your manager, taking the view that if you escalate a formal complaint to HR (in doing so lose all trust you manager and HR may have in you), you’ll be vindicated and live on happily ever after… it’s a fairytale. Go work somewhere that makes you happy. Leave toxic environments - it’s not your job to fix them/right wrongs.
There are certainly real victims in these environments.
There are also in my personal experience a lot of people who make noise/complain about immaterial incidents in the hope of claiming some group control over their situation or with some sense of justice around fixing things. This thrashing can create a toxic environment for those around in itself.
