Turning this into an issue of mere comfort betrays a great deal of privilege. Many, arguably most, people are a firing or two away from poverty and misery. In tech, this can be especially true of people early in their careers, and especially those from less-advantaged backgrounds. If you get fired from your first tech job, and your manager talks a bunch of shit about you, that may be your last tech job.

Even in the current climate employers are desperate for (good) developers, at all points on the experience spectrum.

If you live in a city you can probably get an interview the day after you get fired. Sooner if you're willing to use a recruiter.

While this is true, saying "I got fired from my first and only job in tech. Also I can't provide any professional references because my manager has a grudge against me" can be a red flag for your next employer, or even next few employers (whether justified or not).

Is this still true during Coronavirus? I know my company at least has raised our interview standard
