Is it? Employers use social media extensively today, it's not unexpected that they would re-evaluate an employee's role based on showing solidarity online with a former colleague. Ironic, how we showcase our personal lives online yet become indignant when others take advantage of that accessibility.
Honestly, I'm not really sure what to make of it anymore. Wolf won't come out and say it but it seems like he's suggesting a software engineer would have no qualms picking up a mop and going to town on the vinyl floors. I guess I just don't understand Japan.
