I agree. I almost didn't sign but I also couldn't afford to go without a job. Two years later I'm trying to figure out exactly what I signed because I believe it was very limiting.
That's a weird situation to be in. If they can't reproduce it now they may not be able to produce it at all effectively they've just said they lost your contract which for any self respecting HR department is an absolute failure in their duty. Imagine, if they don't have it, what could have possibly happened to it?
Of does 'unable to produce' translate to 'unwilling to produce'?
