My hospital were happy with my refusal of an induction at 42 weeks (although I never got that far in the end) but there was certainly no pressure to induce as long as I was making an informed choice. I think in many cases the hospitals are just surpised that a woman isn't sick of the pregnancy and ready for the baby to come out, and happy with the assistance offered to make that happen. If you talk through your concerns, and give them a chance to voice theirs, chances are you will come to an agreement you are both happy with (for example regular monitoring, ultrasound of the placental flow, etc).
