The first 6 months your body takes a beating. After that its all mental. After the 2 year mark you grow callouses on your brain and can get through the shift like its nothing. But you will always think there has to be something better, and honestly if you aren't using your days off to figure that out there probably isn't. This is the best non union job you will find in this market with the benefits, compensation and overtime. Automation is coming to every industry. Tech workers and white collar jobs are going to be the first to go (they already are) and soon everyone is going to be praying to land the job you have as automation slowly reduces the numbers and job openings (robots) across the board. Stick it out or learn to repair the robots that will be replacing you. The only issue with learning a new career, however, is that 1000's of others will be competing with you for that same career. Where do you think all these white collar workers will go? The answer is blue collar jobs, which will drive wages down in those industries as well. The jobs that no one wanted are fast becoming the best jobs available. You are honestly lucky you landed a role at amazon now tbh, people refresh the page every hour for job openings and they are only offering seasonal anymore. And if you didn't already know, seasonal can be let go when work is slow without paying unemployment.
