Considering Quitting Before a Write-Up?

I’ve been in the auto loan refinance industry for over two years, and I’m facing a difficult situation: I’m likely to receive a performance improvement plan (PIP) notice by the end of this month due to my declining performance. Until recently, I was regarded as a fairly competent salesperson, but with the rapid changes at my company—particularly concerning client management and the criteria for performance evaluations—I now find myself struggling to meet new expectations.

In my experience with job searching, I’ve often encountered questions about whether I’ve been written up in the past few months. Do employers actually verify this information if I were to say I haven’t? Is this practice legal? I’m based in Colorado and have heard conflicting information regarding what HR departments can disclose. From what I understand, they generally can only confirm basic facts like employment dates and whether I was let go or quit, and not much else.

As I assess my options for leaving my current job, I’d like your advice on the best course of action. Should I quit before I sign any write-up documentation? Would it be better to accept the write-up and then provide my two weeks’ notice next month? What steps can I take to minimize any negative impact on my job search? I appreciate any insights or guidance on how to navigate this challenging situation. Thank you!
