The company should be doing more to support these employees, that’s the point. Right now, Meta doesn’t give a fuck if their employees are getting severely traumatized trying to keep content off their platforms. They don’t pay them much, don’t offer resources for mental health, etc. A maybe bad analogy would be like a construction company having no heavy machinery safety policies and when those employees get hurt and can’t work anymore, just firing them with no worker’s comp.
For comparison, hospitals or law enforcement provide therapy and/or other mental health resources for their employees, since those jobs put their employees in potentially traumatic positions with some frequency (e.g. a doctor/nurse witnessing death a lot).
