Did you say bad thing about your company or sending their trade secrets to China? Snooping your phone may be illegal for your company, Selling their trade secrets, stealing time or other crimes may be worse for you.
OP, if you have proof, you need to be forthcoming with it. There's a lot of technical walls in the way of this happening easily. If you aren't connected to the network or have a device management app on your phone from the company, this is nearly impossible.
Anything that would make it possible is state actor level tech, and that's not going to be floating around a corp office without generating a lot of heat, and they certainly wouldn't be using it for something as stupid as spying on contractors if they did have it.
I am also a techie like you all I am Linux and Windows sys admin could understand how this happened. Even my friends didn’t believe me when I told them initially. Only after I got fired they believed !
I’m sorry, didn’t mean to make light of your situation. My point was unless you gave them access to monitor your phone, they couldn’t have. Only the NSA can do that. They must have monitored you some other way.
OP firstly everything you think has happened is entirely possible. It’s very simple: if you connect your phone to your laptop via charger cable and unlock it then the security software on the laptop will capture it. Most easy if it is backed up in iTunes on that laptop.
Likelihood is you lied about travelling somewhere and they had access to your phone data because it was connected to a laptop and then they fired you
I don’t have to lie, as not much work was going on at the location where I was working. I didn’t connect usually to the laptop may be once or twice I might have connect !!!!! But most of the time I connect to the charger in the plug.
