Zowert there are numerous reasons.
1. Home with the family at a predictable time.
2. Pay is higher.
3. Bonus is much higher. If you do not touch the MIP and DRIP it you should retire with close to or over 7 figures, just don't get fired!
4. I'll get flame to hell and back for this one but management is a much higher stressed job. So if you can handle or even thrive in stress....
5. Some bodies just can not take the pounding that Package dishes out everyday. Think old college sports injuries.
6. Some just don't enjoy physically working outdoors.
7. Some feel they contribute more to the company by managing instead of doing. (OOOO that should piss some readers off!)
8. Some absolutely hate dealing with customers all day.
