Your argument is a bit contradictory: I can skip one day of work just like I can skip 1 workout ("nothing bad will happen").
However, I am pretty sure there are dire/severe consequences to not maintaining your physical health over time [1], just like there are if you do not perform at work.
If nothing happens when you skip one day of work, perhaps you should work less or be fired. In important jobs, not working stalls processes and sometimes even endangers lives.
This feels like grasping at straws here: How do you handle acute illness? Do you just "push through" and potentially get your coworkers sick, all while cranking out sub-par work?
Further, should I be fired or reduce my schedule if I am hospitalized after a car-accident, or require a surgical intervention like the one I 'skipped' 7 days of work to have done?
...The logic of your argument just really doesn't compute, but I may just be missing something.
