I never did that, because I needed the sleep. For me, once my supply was established, two 30-minute sessions sufficed to make milk for the next day, and sometimes a little extra. Other co-workers did three sessions. If you pump once or twice a day before you go back, you can start building up a stash. You don't need weeks and weeks of milk in your stash, but it is nice to have several days' cushion.
If you can pump at home after the first morning feed, do that, so you can take advantage of the supply you built up overnight.
And if it becomes too stressful, feel free to supplement. For me, it was really easy to pump enough milk, so I did it for a year. I wouldn't have done it if it had been a huge struggle, though; once your kid starts eating solids, it's not really as important (it's not like they have some kind of pure gut biome or whatever anymore).
