But you do plan for insurance.
Of course, what's you're point?
What reasons do you have for buying insurance? Can you see where I'm going? You say you don't plan for theft due to employee carelessness, but you bought insurance, so obviously you DID PLAN for that.
No. If I'd planned for the loss of the laptop due to employee carelessness, I would have a lower deductible. If I lost all my IT equipment due to fire, I'm covered. If it's a single laptop, the deductible would not be met and I'd be out of pocket for the cost of the replacement laptop. My rates would increase.
I'd like to turn this around and ask why OP's insurance wouldn't cover this? If this had been a friend's laptop she was using and had in her car, would she expect her friend to eat the cost or would she pay for it?
