Pumping at work

Do u all still carry on pumping when you go back to work? Is your company and colleagues supportive? I’m now feeding my baby breast milk and formula. Was thinking to carry on pumping when I’m back to work even my breastmilk supply not much. Feel got how much then give how much till no more or I should just give him full formula? I’m fully pumping since given birth.. is a tiring process...
