As a career counselor, I normally tell college graduates that the rules will have changed so dramatically since the time they entered college that following the old rules too closely could prove dangerous. It is the equivalent of going to the United Kingdom, where they drive on the left side of the road. You may go knowing how to drive, but many of the rules you learned have changed or no longer apply. When we arrive in this new work wold, we must learn the new set of rules. The employer's commitment to workers is now temporary, lasting as long as there is work to be done.
Employers value the workers' skills, but when the job is done, workers have to move on.
Likewise, workers no longer expect the traditional employment contract. Instead, workers make a commitment to their own craft of portfolio of skills. Much like financial advisers, career advisers are counseling their client to diversify their investment of time and money. Workers need to learn new skills here and there, in order to be less vulnerable to risk . The amount of time spent on each project can fluctuate from time to time, depending on particular issues, and new projects with new employers or partners can be added and dropped as time passes.
