Hi Jill, In the contention between the fs relationship from Task 55 to 56, the (stronger) restriction that Task 56 Must Finish On Tues Dec 4, 2018 is winning the argument, forcing the start date of the 9 day duration Task 56 to start earlier than you'd like. By counting on your fingers and working backward from that Must Finish On of Dec 4 (at 5pm), Task 56 will take:
Dec 4 itself (Tues, 8am - 5pm)
Dec 3 (Mon)
Nov 30 (Fri; after skipping Dec 2 Sun and Dec 1 Sat)
Nov 29 (Thur)
Nov 28 (Wed)
Nov 27 (Tues)
Nov 26 (Mon)
Nov 22 (Wed; after skipping Nov 25 Sun, Nov 24 Sat, plus Nov 23 Fri and Nov 22 Thur as your Scheduled Thanksgiving days)
Nov 21 (Tues at 8am)...just as Workfront is showing to you
Put another way: there simply isn't enough time for a 9 day Task that starts at 5pm on Nov 20 and have it finish by 5pm on Dec 4: it has to start at 8am. If you can shave that duration to 8 days (or have folks work an extra hour per day, or only take 1 day for Thanksgiving, or push the Must Finish on to Dec 5, etc.), you could Make It Fit...but perhaps knowing now that it's going to be tight is Good Enough.
