Should I take this job?

If it weren’t for the taking 4 buses a day during a pandemic thing, I’d be joining the “take any shitty job” chorus. But you are absolutely right that this would raise your risk of infection from minuscule to highly likely. And if you do get infected, even if you’re healthy with none of the risk factors we keep hearing about, your risk of death, permanent disability, or at least long-term damage is uncomfortably high. If you can find another way to get to work, and if you don’t have to be too close to your co-workers, maybe it’s a risk worth taking. But if you can’t, and you’re sitting on 2 years’ living expenses, I’d try to ride this out.

Can you use the time to train or study for a better job?
