The option to quit and only work either every other year or every 6 months is more viable. Though still job/industry specific, many people pull this off.
It’s up to the individual if doing animation work in 6 month bursts for individual movies is enough or if they want near full time employment. 6 month rotations are common in many tiny industries like super yacht crews. Major industries like education, farming, construction, and tourism are quite seasonal and it’s up to individuals if they take that time off or work an off season job.
