I remember practices similar to this, though less extreme, at a sub-manufacturing plant in the auto industry that I worked at when I was younger. Some people began to get upset and act against it--ie, shut down their machines early to cover the spread. They received some very hard pushback from supervisors, then management. It blew up into a full-blown unionization campaign, with the Canadian Auto Workers union representatives stationed outside exit streets from the plant meeting with employees as they left for the day to promote their position, and the company electing to hand out anti-union pamphlets, put up anti-union flyers all over the grounds (halls, break rooms, change rooms, plant floor), and host meetings where they would slyly threaten to close the plant and move it away. It got ugly. And that was over a combined ~30 minutes a day maybe. I'd be pretty upset over being held after work for an hour for a search. (I've had that experience in college working for a major chocolate/candy manufacturer but it never took more than 20 seconds. I still thought that was ridiculous to search our bags for little plastic noisemaker boxes of candy breath mints that couldn't cost more than a few cents).
