What kind of pump are you using? Do your horns fit that breast correctly? Are you doing anything to "lube" up the horns to make pumping more comfortable?
In short, if baby actually drinks a reasonable amount from that side (It's possible that baby doesn't drink as much from that side either ... many women have one breast that produces less than the other), you may end up with clogged ducts, which can lead to mastitis. If baby regularly takes a normal amount of milk from that breast and you don't pump a normal amount of milk from that breast, your breast may become engorged, develop clogs, etc. You can also try using breast compressions to help empty that breast. Also, follow up w/ hand expression.
Get back to us about the pump and we'll see if we can help.
Any chance you can get out of the trip? Many offices don't realize what a burden it is for a nursing mom to leave baby for several days. But when mom lets them know it might be a problem, she is able to bring baby with her or they find someone else to go if possible.
Might be worth exploring.

Cilla, don’t worry about the breasts producing different amounts. All of us have ‘lopsided’ breasts/production. Sometimes babies will prefer the bigger producer but that’s ok. Some moms find as the baby gets older they will hardly take or not take the lower producer at all. I have seen babies begin refusing one breast and then continue to breastfeed for a long time after on just the other breast. It’s possible to breastfeed on just one breast if that’s what happens. (Don’t forget twins only have one breast per baby)
