A teacher year is 180 days. 1/2 year is 90 days. 2 years is 360 days. Letâs say the teacher wants to exchange accumulated sick leave, for years of service credit, so they can retire earlier.
Fatigue is a lingering tiredness that is constant and limiting. With fatigue, you have unexplained, persistent, and relapsing exhaustion. It's similar to how you feel when you have the flu or have missed a lot of sleep. If you have chronic fatigue,, or systemic exertion intolerance disease (SEID), you may wake in the morning feeling as though you've not slept.
I hope this information is of some help to you. Tiredness is caused because the body is trying to heal. It is making adjustment (homeostatis) to try to do the functions the liver once did. The tiredness can be sudden and unforgiving. There is no choice but for the body to sleep.
