I agree that there may be some workplace awards that don't spell out in black and white that you have a right to express, but you certainly can't be discriminated against. Regardless of that policy, they are obliged to provide a space to express and suitable storage.

In my situation I choose to use the lunch break and 2 tea breaks my employer offered to eveyone to express, and with a manual pump could complete in about 10 mins. it wasn't long before bubs cut down feeds and I could slowly reduce when I expressed.

The hardest part for me was that I work in an office environment and it is difficult to get a room to express in without having to ask and I don't think I should have to ask to use the HR managers office.
