Pros
Healthcare and paid time off start when you are hired, there is no probationary period.
You can listen to music, read, draw or sketch while running work, as long as you are doing your job.
Work is intellectually stimulating, if you like puzzles you may enjoy problem-solving machine issues. You could learn new things for years.
The way shifts are laid out you get three days off Fri-Sat every other week, you get your schedule for the entire year at the beginning of the year.
Good coworkers. The majority of the people who work there are nice, and the environment is more casual than customer-facing jobs.
Cons
The work is physically difficult, you're on your feet for a good deal of 12 hours and sometimes you're lifting a lot of heavy boxes.
It can also be mentally challenging, with multiple things to attend at the same time and a lot of adjusting machine settings. It is also repetitive work overall.
Sometimes it's stressful because of deadlines or production expectations.
The learning curve is kind of steep. The first couple of months are the hardest; there is a lot of nuance to running the machines and it is a lot easier after you get more familiar and skilled. Most people are frustrated or discouraged some of the time while they are learning.
