Pumping and work

Kris🐶🐶👶🏼
Imcurrently pumping 7-8 times aday (including middle of the night when i feed the baby i pump to) 
When i go back to work 😖 will i be able to cut back on pumping so much without a drastic drop in supply and without my boobs feeling like there going to explode?? I really dont want to have to pump at work especially not every 3 hours.
