I don’t think it’s reasonable to expect that because you took a position, you forfeit any rights to decide a company has crossed your ethical line in the sand, or that you shouldn’t use a unique opportunity–even at your own risk–to appeal to other employees and leadership to adjust course. Growing up, I was told by family, mentors, educators that you effect change from within. Protest only when it’s safe and convenient is easily dismissed thus counterproductive.

It’s up to the individual to decide if this employee was right or wrong about the issue at hand, but puzzling over whether or not they’re some sort of fool for strongly believing in something seems a bit obtuse.
