A woman in my team is leaving to go a rival business. When she handed in her notice I was pleased, as her performance had been pretty dreadful for a long time - slapdash and chaotic work, refusal to take responsibility for her area, lack of focus etc. She's very sweet though, and a nice person to have around the place. However, the area she covers in my team is too important for this to continue, so I had begun a formal disciplinary process with her, all agreed with by my boss and HR. Obviously not pleasant, hence why I was relieved when she resigned.
I've now been sent a reference request from her new employer, and it's much more detailed than I would have expected. It doesn't ask for me to 'write' anything, which I could have fudged a bit, but instead to give specific ratings for her performance in various areas, and asks the direct question: Would you hire this person again?
The truthful answer is obviously 'No', but I'm not sure what to do. I don't want to sabotage this woman's career (and in a self-interested way I very definitely want her to leave!) but I also don't want to lie. WWYD?
