Sure, but you're already treading in murky legal waters.
Just this posting could be viewed as Amazon trying to create the impression that it is actively surveilling labor organizing activities, which it's illegal to suggest, even if you're not actually engaging in that practice.
What is illegal in surveilling employees during work hour on workplace or on work device? It's not like amazon is bugging the house of workers. In all the companies I worked, I am pretty sure I signed contract allowing that. It's a different story that I have technical ability to turn off all the remote disable/access software they install on my work device.
It is, apparently, the case that creating an environment where a reasonable person would feel surveilled is in violation of the law.
Concrete things that are highlighted as out-of-bounds:
1) Putting a dummy security camera in a breakroom
2) Hiring someone to sit in a car in the company parking lot and pretend to talk into a phone every time someone goes to their car
Given that wide constraint, I can definitely see how "hiring an intelligence analyst who would specifically be tasked with keeping the company high-level leadership informed about labor threats to the company" could be interpreted, reasonable-person-wise, as the company surveilling organized labor. I don't think it's the slam-dunk some are describing it as, but it's, if you will, "a bad look."
Are we talking about being unethical or illegal? I think putting even a real camera in breakout room is legal in almost all of the world. If the second story is correct, which I doubt, even that could be legal. Attendance system is used by many companies with report being sent to manager.
Apologies; I misremembered the details of the second example.
"having a supervisor sit in a car while observing union activity and talking on the phone, even if the conversation is not a report on the union activity."
Cal. Acrylic Indus., 322 N.L.R.B. 41, 59 (1996) ("whether a video tape was actually in
Saldana's video camera or whether he actually pressed down on the record button .. . the 'chilling
effect' of such on Respondent's employees' Section 7 rights was the same.").
