A vision of the future cannot be decreed. It is not enough to
say "you need to think about it" in order for ideas and desire to burst
forth.
It is better on the contrary to downplay the difficulties
your-co-worker may have in projecting himself forward and to reassure
him: no one is asking him to lay out a 10-year career plan or
to identify definitively a new job for himself!
The first manifestations of the future are sometimes right in
front of our eyes. It's then a question of helping the co-worker to
perceive and to understand them: what things in your current
position are already in the process of evolving? What has
changed in your job over the past few years and what still might change,
perhaps inconspicuously? What knowledge or skills would be
even more useful a few months or years from now? ... etc.
Envision a first step toward preparing the future
The preceding questions generally allow the identification of
vectors to work on to maintain or reinforce one's employability.
The actions to undertake might be of various natures:
researching information on a profession, a market, or on certain
practices; enriching one's current position, especially by cross-sector
activities, receiving training...
The aim is to develop an education in adaptability.
