The most dangerous illusion in the workplace is thinking that "as long as I do my job well, it doesn't matter whether I speak up or not in meetings."

You're completely wrong. The essence of meetings is to confirm the "value anchor."
When the layoff list is presented to the boss, what he is searching for in his mind is:
Who can solve the problem? Who proposed suggestions at the last minute? Who can withstand the pressure?
And the person who remains silent at every meeting is a blank in the boss's memory. A blank is the easiest part to erase.
You may not have groundbreaking insights, but you must have your voice. Silence is providing the person making layoffs with a "psychological convenience"—firing someone who has no sense of presence leaves them with no psychological burden.
