Note that body cameras are outfacing and police officers uniquely wield the power of life and death as agents of the state, with a long and rather sordid track record of abusing that power, making arguments for surveillance particularly compelling.
Police officers are powerful people, truckers are not. They are often very poorly paid and forced to accept jobs they don't want just to survive.
But even if that were not the case, long-haul trucking companies are putting face-forward surveillance in place when they don't to. As the author of the piece notes, these companies have alternatives for monitoring safer operating conditions that do not involve intrusive, face-forward surveillance.
Workers need to be treated as human beings with inherent dignity and value. Not as cogs to be surveilled and controlled by faceless corporate managers
