Junior Flight Attendants (i.e. new-hires) often carry the brunt of the job because they frequently work less than 50 hours or less per month, making it very difficult to make ends meet financially. Reserves are usually guaranteed to be paid for at least 65 hours per month (it varies between airlines), and that helps.
Hypoglycemia, also known as low blood sugar, is when blood sugar decreases to below normal levels. This may result in a variety of symptoms including clumsiness, trouble talking, confusion, loss of consciousness, seizures, or death. A feeling of hunger, sweating, shakiness, and weakness may also be present. Symptoms typically come on quickly.
Hypoglycemia (sometimes called sugar shock, low blood sugar, sugar down) is a condition where the blood sugar level drops to an extremely low level, usually due to lack of food, or by using up all stored energy without it being replenished (playing/running for extended periods of time, shivering out of nervousness or being chilled, stress, etc...) without eating to replenish their energy teacups can end up with hypoglycemia.
