First of all i have very little knowledge in these things. I am just copy pasting the things mentioned in the book.

1. But what if the person already bought the ticket for two weeks, but he basically can finish his works anytime in between and can go home anytime in between?

Sorry bro, i dont know the answer.

2. Is Friday prayer obligatory for that person?
The following is the condition of who are obliged to pray Juma'a according to Shafi'i Madhab.

f18.2
Anyone obliged to pray the noon prayer (zuhr) is obliged to pray the Friday prayer (jumu`a),
except for
-women and
-for travellers on a trip that is not disobedience , even if the trip is less that 81 km/50 mi. one way (n: though one's departure for the journey must have taken place before dawn on Friday, as at f18.6).
-Valid excuses for not attending group prayer (def: f12.5), such as illness or taking care of a sick person, excuse one from attending the Friday prayer (jumu`a).
f18.6 It is unlawful for someone (obliged to pray the Friday prayer) to travel after dawn (on Friday before having prayed it) unless:
(1) there is a place on his route where the Friday prayer will take place;
(2) or he is going to travel with a group (of people not obliged to pray the Friday prayer) who
are departing, such that his staying behind would entail harm for him.
So what I understand is, only conditions that a traveler is excused from Juma'a are:
-if the traveler begins his journey before dawn
-The traveler begins the journey after dawn with a group of people (who are not obliged to pray Juma'a) because he couldn't stay back for something harmful.
