Indeed. I have refused signing such contracts.

One funny anecdote, I went through a relatively lengthy recruitment process for a company. The company, the role, the team, the tech, everything was interesting and enticing. We eventually agreed on compensation and the process moved on. I asked for a copy of the contract minutes before they had everything ready so I could read it without causing delays, which they complied.

I pointed out a few minor details but this one was sticking out so I was pretty clear that I was bothered by that. After a few of their tentatives to explain why and convince me it was fine and that clause had never been enforced, and that my comments had reignited internal conversations about this, in one call I was told they were in advanced talks with legal to make the change.

I told them I would be delighted to be in touch again when the clause was removed from my contract.

They never called back. :)
