If this is really the case, and you can survive without this job, you should consider walking. Your employer has demonstrated that they do not care about you or others on your team who are being pushed to continue showing up. And your employer, with this kind of approach, does not deserve any of your loyalty.

It's bad that some employers are still pushing people to show up for non-essential work. It's an entirely different level when people are showing up symptomatic, and still being pushed to show up.

Edit: I meant to add, that you'd probably be supporting your team by walking if you can. The more people who walk, the more clear it becomes that the employer is in an untenable position.
