There's a big mistake that 99% of employees are making and they don't even know it. This mistake is being made primarily by people who are new in their career, but it's also being made by veterans who see the writing on the wall but are ignoring the signs and symptoms. The big mistake is the false sense of security employees are establishing in their careers. It's not their fault, though.

This question is no longer applicable nor should it be allowed to be asked, especially in the context of white collar jobs. As we go through life, graduate from high school, and head off to college, this antiquated and false sense of security is pushed even further, as colleges and universities try to narrow the lane students fit in. In the real world, things don't work like that. In the real world in 2014 and beyond, you can no longer establish a career based on a single field. Your employer doesn't need 100 people who are experts in one particular field. They need 100 people who are Jacks-Of-All-Trades. They need people who understand and can speak the lingo across teams and across departments.

They constantly evolve and change. The problem with this change is that it leaves the employee vulnerable to losing their job as their chosen field may eventually become obsolete. So, here's the formula for success:
