It is my experience that whenever someone utters the line, "it takes a certain type of person" that bad news is to come.
To summarize, corporate crew can expect:
1. No schedule
2. No time off
3. No support
4. No respect
5. No duty rest
6. No life outside work
This leads me to wonder, exactly, what type of person does it take?! Not a very smart one. Sorry to be negative but seems quite narcissistic to me, particularly for those with actual family or friends outside work.
