Per your question: > She submitted her resignation Great, start the knowledge transfer/documentation process. She has checked out mentally; say your farewells. ---------- This is a load of hogwash and you know it. > Policy in the company doesn't allow raises before finishing the first year of employment. ---------- What positive outcome do you foresee by convincing them to stay? Her staying only benefits you as you have clearly expressed in the hogwash above. During my most recent job change management decided to match my new company's offer within 2 days of me providing my resignation letter, effective immediately if I accepted, which was a 24% raise. Do you think I felt humbled that the company graciously underpaid me for years? No, I was checked out; good luck to the company.
