I had that happen to a team member (me as a manager). She came to give me notice, the pay jump was huge. 45k to 70k. I loved her and I tried to swing it with my boss, but the ultimate answer was no and she left. I hope she is happy now. She really was awesome and I wish she stayed working for me, but I’m happy for her. She was a single mom to 2 teenagers so there’s no way she couldn’t accept that money
