When it comes to a job, your job perhaps, there is no absolute security really. Things could change at any company or organization that require a change in the job landscape. In such cases where change happens, there is not much an individual could do about that.
Having said that, there are things that you could do to sustain your job or career and they are rather simple policies that you could follow. They all center around respecting your job. If your job is what is funding your very living and lifestyle, then I would think that showing the greatest respect for your job should come naturally. But what does that mean?
Well, being very respectful of the requirements of the job is a starting point. Show up on time and stay until you are supposed to stay and do what you are required to do in between is a minimum. There is a lot more to it.
Here is a perspective that works. Think of how you would approach your job if you were a major stakeholder in the business and your very performance could determine the survival and success of the company. What would expect yourself to do if you were the owner of the business? You would probably be very judicious with your time and with your efforts to give your very best. Well, take that approach and see what happens.
Continuous learning about your field of specialty is also a key to success. Continue to look for ways to learn and grow in your profession. Read every day. Attend seminars. Converse with other people who have been successful in your same field. Make every day another step in your personal success and the success of your company. If you don't feel a need to make your company successful, then you should consider looking elsewhere.
There are ways to help to not only sustain but to grow your career and job. It does start with respecting the job and doing things to get better every day.
