I heard a person call into a show the other day, voice only, and talk about some poor working conditions at a factory. Made me think about how it would probably be so easy for nefarious bosses to be able to identify that person with all of the data that comes from us looking directly into cameras and speaking clearly in modern workplaces.
Do “anonymous” callers need to start using voice modulation software for these kinds of calls in the modern world?
In general, if something is possible to exploit, some companies will exploit it.
Figuring out which ones do can be difficult-to-impossible, since that information is not usually available to the public, or in many cases even to most employees. Unless a whistleblower steps forward, the best we can do is guess, and take whatever precautions we feel are worthwhile.
