adam parrish's three jobs
A semi-comprehensive compilation of canon information about adam's part-time jobs:
Adam held down three jobs, the most important of which
was at the trailer factory just outside Henrietta.
At eight P.M., Gansey called Adam at the trailer factory.
"You didn’t tell me you were making [...] eighteen thousand, four hundred and twenty-three dollars a year!”
And then there were the three part-time jobs that paid his Aglionby
tuition. He crammed in the work hours now to afford a more leisurely fall
when school started. He’d spent just two hours at the easiest of the jobs —
Boyd’s Body & Paint, LLC, replacing brake pads and changing oil and
finding what was making that squeaking noise...
The first day was the easiest, of course. Before it had really all begun [...] Before Adam’s night job and
studying until three A.M. conspired to destroy him.
Adam was alone in the shop.
In the still-rainy evening [...] Boyd had set him on the task of
[...] closing up shop. Dinner, he said, was for old
men like him. [...] Adam retorted, “What’s it you see me doing right now? [...] I’m at work. Two hours from now, I’m going to my next job for
another four hours."
Adam squinted against the colourless new dawn [...] it felt like only minutes had passed since he’d emerged from his night shift at the factory.
Adam Parrish was working. He had a late shift at the warehouse that night,
unloading mason jars and cheap electronics and puzzles.
so if we're taking the books by word (which, I mean, we kind of have to, although I can make the argument that they're often inconsistent), it seems like adam works these three jobs:
a job at a trailer factory at nights, implied to be (at least sometimes) eight p.m. to midnight. this one earns him the most money (=the most important). going by estimations of hourly wages for manufacturing night shifts in virginia circa-2011, this would be 14$-18$ per hour.
a job as a mechanic at boyd's, where he seems to work non-regular shifts, but at least occasionally in the evenings, likely around four p.m. to eight p.m.; going by estimations of hourly wages for working as a mechanic (without much experience) in virginia circa-2011, this would be 9$-11$ per hour.
and a job at a warehouse, which reads as separate to the factory job because of the items mentioned. it's only mentioned once, so it's hard to determine if it's only at nights, but it definitely isn't every night. if he worked exclusively nights, the hourly wage estimation would be 10$-13$ per hour.
robert claims adam made 18,423 dollars a year. that's 353$ a week on average. we can deduce that he made more money during summer break than he did during the school year, so let's assume he made around 300$ a week during the year.
that would mean his schedule went something like this:
3 weekly night shifts at the trailer factory
1-2 weekly shifts at boyd's
1 night shift at the warehouse
(on top of, you know. literally everything else he had going on.)
