I'd probably also send them a bill for the cost to me, in time and effort, or restoring all my data.

The simple answer is not to store company email on your phone. Then you shouldn't have to worry about this.

I parked my personal car in the company fleet car garage and they clamped it. I didn't understand what was happening and called the rescue company telling them it had broken down and wasted lots of time.

This was so unfair I quit that day, causing a dramatic fuss pointing out exactly how much they'll suffer. That'll show them.

Imagine today one of your employees quits on the spot, tells you he's quitting because his car was clamped.

You have no idea who manages the parking lot, but now you just lost a resource on your project.

How did your manager end up reacting?

Not a true story, an attempt to frame the parent post I was replying to in a different light to show how much of a prima Donna overreaction it would be, and as you say, directed at the wrong people too.

Your analogy would be more apt if you once parked your car in the company lot, and then years later some IT guy sneaks into your house at night and clamps your car.

But you agreed to stick business data on your personal phone.
