Hermetically sealed?
Does your role protect you from the cold winds of commercial reality? Is your primary skill being able to operate below the redundancy radar thus keeping yourself in employment?
It is perfectly natural to do this. Many organisations pay people on a time basis so the natural response is to do as little as possible for the maximum amount of time. And if you work for a large and /or inefficient organisation you may enjoy a career based around maximising the return on your labour.
But increasingly more firm are facing the cold commercial realities and are thus having to ‘right size’ their workforce in a ruthless manner. Increasingly there is no place to hide and soon those not focused on productivity will find themselves sitting outside the tent feeling the full force of the tundra winds.
The point is that even though the industrial era working environment encourages work-avoidance, it makes sense to take this paid opportunity (your current role) to deepen your skills regardless of the financial return. Think of it as employment insurance or more simply a more productive and meaningful way to spend a large chunk of your life.
