I was a photojournalist for a while. We had to tread lightly because I worked on college campuses. So, the people I worked for had to run around and get releases before they could use the images in college publications (not student ones).
Blurring folks would be fine from the image point of view. If their voice is identifying…I would imagine the same constraints would apply.
In another world, I managed service people who spent all day dealing with the public. I would not be happy, as their boss, if they were taping my customers in order to “make fun of them.”
Now, if you are the union steward you should probably run this idea by your union lawyer. It might be misconstrued by your employer as some sort of “safety issue” and what if, in the end, they wanted all of your peers to wear body cams that would have to be activated all day long. I am pretty sure some of my old service guys spent more than an hour or so—once in a while—parked behind the local grocery store out of sight from the street. Taking a nap. I am pretty sure the Union would not want to deal with THAT. LOL.
Yeah well that bs scenario is already out of bounds anyway. I am position GPS every 10 seconds anyway. The days of napping or 2 martini lunches went out with the turn of the century management. Not pitching, just stating fact. The scanner has become every honest workers friend. No fear.
