“Even when you don’t agree with decisions the company leadership is making, part of your job is representing and facilitating those decisions with full alignment. When acting “in public” (all-hands, department meetings, the #general channel), this is mandatory, as contradicting the bosses in a broad forum can kill the credibility you have the leadership across the wider team“

Take this advice with a grain of salt. If bad decisions can lead to very bad things and you know it you must push back even if that means getting fired. This is particularly important when the life and wellbeing of others are at stake. Just look at Boeing to see how prioritizing a job over ethics can actually kill people and destroy companies.
