Thinking about this, that&#x27;s basically equivalent to, in America, handing out your American W2 tax forms instead of references. The forms give a duration for which each company had you on payroll, plus a separation code (layoff, quit, fired with&#x2F;without cause) if you&#x27;re no longer there.<p>Sure, they also show how much you were being paid, but presumably you could wait until after a salary negotiation to hand these over.
