On the layoff list, there were hundreds of people in the whole factory, but I, the technician, was the only one who was laid off. The boss looked disdainful; "Without you, the factory will continue as usual." I didn't argue, signed and left silently, without anyone trying to stay. Just five days later, the boss called angrily. The production line was completely shut down, and everyone was helpless. He probably never thought that the technician he regarded as dispensable was the key to the entire production line. This time, I won't look back.
