You can take loa from this job for any reason. I know a lot of people who work less hrs to get insurance but still go on loa. if you do go longer than one month and you work enough hrs for insurance your insurance over laps by +1 month. Just do 16 hrs weekly for health insurance for single person 20 to be safe. 60 or 80 hrs a week for family.
and what is the reason not to do it? I know many who have encountered this problem, so I would solve this issue in the near future, for your own restful sleep
