The "or any other issues" is extremely broad, and seems reckless. When an employee then tried to _internally_ escalate a concern, that employee was suspended and fired. A minimal slap on the wrist means that Tesla is likely to continue to suppress discussions of wages or workplace conditions, which sucks for workers -- but if the message coming out of this is that escalating _any_ concern above local management is likely to get you fired, I wonder what other kinds of issues will go unaddressed? Workplace safety issues? _Product_ safety issues? Would some of the quality control issues that were in the press some time ago have been more quickly addressed if internal communication didn't put people at risk of being fired?

An organization in which people cannot honestly escalate concerns _internally_ is dysfunctional, and has the potential to create harms for customers and shareholders in addition to employees.

HR should probably be more on the ball too. And implemented policies/procedures.

There's never just one person who messes up. Kinda like how it's never just the Junior Dev's fault when they delete the production database.
