At some point as a collective we MUST realize our labour is the reason things are running (free movement of goods and people, skydiving, air recon etc...). As an individual, I don't hesitate to point the finger at sh*t conditions when I see them and answer to these kinds of mails in consequence. Being honest is enough, you can't expect to behave like a miserable insect and receive respect from the massive boot that is crushing us with these working conditions.
Man the eff up. I had little leverage to make my job refusals impact the grand scheme of things in the past, but my job prospects improved and telling the truth to these slavers improves pride greatly (for those that still have some).
