Tl;Dr. Amazon Warehouse in Colorado Springs is using an illegal phone jammer in their warehouse/recruiting site.
I was getting desperate for a job so I bit the bullet & applied to Amazon, go in to do the precise screening & drug test & they tell me I missed a document online that I need to do real quick.
I go to pull it up from my email & there is no signal at all (grayed out with the small x over the icon for signal bars) & she informs me we need to connect our phones to the wifi to check email so I say something along the lines “im not giving you access to my device, why isn't my phone working? Is there some kind of signal jammer?”
The lady handling my stuff says it's just the way the facility is built” but is cut off from one of her coworkers saying that “There is a phone jammer to ensure workers aren't using their phones during the job”
I noped right out of there and reported them to the FCC and CO state law enforcement.
Phone jammers are illegal in almost every context, with the only exceptions being military and federal law enforcement, and even then, there are restrictions.
They are illegal because they prevent people from calling for help in the case of emergency.
If your workplace has a phone, jammer report it to your state officials and the FCC.
