Give me a break. Workers have a right to address their employer over grievances but considering how many people are going to be negatively impacted by their antics with this, THEY are the ones committing the sin. When you have a responsibility or an impact on other people's lives and livelihood, acting irresponsibly is the sinful act, not the person calling them on it.

Find another way to fix your problems instead of negatively impacting billions of people who are completely unrelated to you or your grievances. 

 And what are they to do when they have tried other means of redress unsuccessfully?

Our country was founded on a rebellion, we ought to understand those who resort to protest when they believe their voices are not being heard. 

 Find another job instead of costing others their jobs, ruining the lives of millions of innocent peoole, and preventing the arrival aid for desperate people in a disaster zone. No matter how you frame this, it's unadulterated selfishness and I hope everyone involved with this loses their job.
