Getting feedback from your employees is always a good idea. When they first start in your business is a good time to start. Once a new employee has come in and undergone the induction programme, you have a unique opportunity to get feedback on how thorough and helpful this was for the new employee. Don't take it as criticism, take it as a form of continual improvement. Good employees give helpful positive feedback to employers, and this should be encouraged at all times. No employer has their HR at 10 out of ten - but that's the goal, and getting feedback at every stage is one way to take steps toward achieving that.
