In general, manufacturing can have repetitive, monotonous tasks which are tied to cycle times and a desired production output number. There is possibility of exposure to noise, lifting, walking, pushing, pulling, use of rotating tools, sharp objects, flying debris, chemicals, and poor air quality to name a few.
Pay is often good but work can be cyclical in that sales can dip causing a decrease in demand. Also, product can be discontinued leading to plant closures.
I hope this gives you a better idea and hopefully allows you to better decide what type of job you are looking for.
I agree with Karla and Steven. I spent a few years in automotive at a Chevy plant. While I was in an engineering role, I interacted with workers on the shop floor and in maintenance. There are a lot of options and job types in automotive. Review the job postings around where you live to see what jobs are of interest, and if you have the qualifications to apply. If you are not currently qualified, look into the training required and assess if it is something that you can do outside of work hours while you work in a different role either in automotive or in another field.
Hope this helps,
