Your perspective is quite distorted. It's Apple's prerogative if they want to subject their employees to searches but if they are going to force their employees to do so the employees should be compensated for their time that they would otherwise have for their own lives; cost of doing business. You're right though, worker's rights do make labor more expensive by definition but that is not necessarily a bad thing .e.g consider how making slavery illegal was very expensive for businesses at the time.
