Hope all went well for you, I was also in naknek this season for silver bay seafoods. I saw some discontent for a lot of the canneries here and while yes the work is shit, I did most jobs at least once but I was mostly on case up and the fillet line, it wasnt that bad for me.
The bad: Aside from the long hours (16 hour days the whole time I was there) I would have swollen fingers in the morning which I cured with anti inflammatory ibuprofen which I brought a few bottles of. I was sometimes tired due to lack of sleep but I also had caffeine pills, but coffee was also abundant and free inside the mess hall/break hall. My feet hurt at first with the company provided boots but when I got the extra tuffs with insoles my feet were fine, also had wool socks so my toes were not cold. the breaks were also bullshit because they started when they told you to go so you had to get undressed and redressed in your break time, leaving time for a hot beverage and a smoke for me personally. HR didnt transfer me
The good: Fat fucking checks for me personally. The work itself was not hard at all. I had brought my phone loaded up with 300 gigs of tv shows and movies, some of which I actually got to watch lmao. They had internet accessible machines for me to update friends/family/whoever on my condition and order some amazon packages to enjoy when I got home. The food was pretty good where I was at, but that tends to vary between places and more importantly companies. I wasnt super micro managed, only given a heads up when I was caught slacking off, got yelled at once for "breaking the fish" when I was throwing frozen fish onto the belt but didnt even get a write up.
So if anyone brings shit like icy hot or anti inflammatory drugs and xtra tuff boots I think the rest of your stay will be great, maybe even some emergen-C, the only thing terribly bad was the boredom and sometimes I couldnt even talk to my co-workers due to language barrier but that was fine. Its a good job if you have specific goals for that money such as travel or school or getting a new car or whatever its a job thats monotonous as fuck but the pay was worth it for me.
