> I don't do this any more. I realized after a couple of these jobs that this level of explicit disrespect written into a contract pretty much tells you all you need to know about working there before you've even joined.

Tbh, we had this come up when we purchased and I negotiated it out of my "new" hiring contract successfully.

So far everyone I have on LinkedIn at #ParentCompany has quit but my little isolated bubble trundles on largely immune to such problems as long as we hit our sales/profit numbers.

So I suspect you are correct in some cases but you can still sit in protected bubbles that have that in the contract AND are still worth working for.
