We live in a blatantly corrupt world and smart people engage in the wise practice of risk management.

This fits in with what I saw in staff in astronomical facilities and was reporting to the management team: 10-14% Oxygen: Emotional upset, abnormal fatigue, disturbed respiration.

I made the mistake of using my earned sick time at the W. M. Keck Observatory for essential surgery. When I returned to work the management team demanded my resignation numerous times, citing my essential surgery as a reason. The W. M. Keck Observatory taught me that using earned sick time in the USA may put your future employment at significant risk.
