It sucks that that counts as lucky in today’s job market, but it does and I get what you’re saying. I’m sorry GitHub allowed this unsafe workplace for you and other Jewish employees. That’s just not okay. This mistake us 100% on them and I hope they’ve learned from it.
People deserve to contribute their talents and knowledge to workplaces that do the sort of work GitHub does without fear of retaliation for speaking truth to power, not to mention warning others of danger.
