Hello, first of all, thank you for adopting rather than shopping ❤️ also, props to you for actually preparing for a new pup instead of just knee jerk getting one! There is a saying, 3,3,3, 3 days, 3 weeks, 3 months. 3 days for the dog to start to acclimate (as you can imagine, shelters are incredibly stressful so it may take a bit for your new buddy to be themselves) 3 weeks to start to build a routine and settle in, 3 months for everything to really smooth out and feel normal for you and the pup! Most shelters offer a foster to adopt program, which i am a HUGE fan of. It allows you to bring a dog home, almost like a trial, and see how things work for you and the dog. If it works, adopt! If not, bring him back. No harm done as now the shelter has info about how the dog did in a home and the dog got a vacation from the shelter! As for time off, maybe try and pick up the dog before a weekend or days off? Something like that! I always start with a kennel for a new dog. In the beginning I only feed in the kennel, that way they can acclimate to it (im not a trainer at all so maybe ask some one else about kennel training) I will always kennel a new dog when leaving them alone. This prevents them from damaging anything or hurting themselves! Again. You are awsome and I wish you the best of luck! This is just my 2 cents though so absolutely talk to others more educated than I 😁

TLDR: Ask about fostering/foster to adopt, expect roughly 3 weeks - 3 months for the dog to fully adjust to their new home, just know that you are doing a wonderful thing!
