Not to say these policies are grand or the working conditions are anywhere near reasonable just that the claim from the lawsuit it was a disability violation seems like it will be difficult to argue vs just being a shitty place to work.
Any time my doctor says something affects my work, I ask her for a letter in my medical record and keep a copy for myself.
This seems pretty straightforward and odd that a letter didn’t exist in the first place.
This whole store lacks enough detail to know exactly what's going on, however, so we're all going to project our biases on it. If you're anti-Amazon you're going to project your assumptions of unfair business practices. If you're skeptical of that position you're going to project your skepticism into the unknowns of the story. Really there aren't enough facts here to know if this is Amazon firing an underperforming employee who is lying about a health condition, or failing to accommodate an employee with a legitimate health problem.
