Your employability is your security and improving soft skills is key.
Writers at the turn of the century predicted a new career in which our future security would be dependent on developing key characteristics, specifically employability and resilience. They are still right. Employability has evolved to encompass a range of 21st century skills - self-direction to navigate change, adaptability to accept the challenges of change, inventive thinking for innovation and creativity, and continuous learning to manage the complexity of technology and globalisation, and keep up with new tasks. But recent world-wide surveys tell us mastering complex work skills is not enough; there is a shortage of workers with highly desirable personal or 'soft' skills including the all-encompassing attribute of professionalism. Just an agreeable personality won't do - these are skills to target and systematically develop, as they add significantly to your ability to work in a wide range of sectors or roles.
So if you want to be the highly employable worker, the successful self-employed business owner or contract worker, or all of these at various times, consider these:
Display professionalism
Develop the Professional You. This is the person who demonstrates increasing competence, good communication, integrity, high standards of work commitment and conduct, and a productive approach: it's the whole package. Employers want the professional you at work, and they want you to leave the casual you at home. They want the productive you, not the social you. Become a true professional and you will raise your profile as a wanted worker.
Add value with advanced skills
Whatever you work at, aim to be very good at it and keep improving. Understand every craft has advanced skills and set about learning them. This alone will take you beyond the mediocre and into the ranks of talent. The pace of change will keep making demands, and your workplace will offer you learning opportunities and challenges. Don't grumble, grab them. You benefit as you get to transfer those skills with you to new opportunities.
