I work in a large public hospital and we are lucky enough to have a small staff breastfeeding room with TV, fridge and lounge suites to pump in. There can be more than one person in there feeding or pumping at a time. We are also able to use the hospitals pumps but need to provide our own attatchements/storage containers. Up until the baby is 12 months old we are also entitled to take up to another 30 minutes paid break per 8 hour shift to express/feed. I never needed to take all this extra time but an extra 15 mintues meant I got to pump twice while at work and have a hot meal.

Have you checked the ABA's website? I think they have a booklet on your rights in regards to breastfeeding and work. i think your employer has a responsibility to provide you with a clean private space to feed or express.

Good luck going back to work.
