Making yourself indispensable during hard times

Many companies are laying people off in attempt to cut cost during these hard times.
If you are employed, your company may be next to lay people off.
So how do you make yourself indispensable or at least one of the last few standing?
Well, I wish there was one answer to this question but it is a combination of things and if you have not been doing it, you better get busy!
1. Make sure you are well qualified for the responsibilities you were hired to do.
2. Continue to improve and learn new things on the job.
3. Continued education: get more certification, membership to relevant organizations etc.
4. Relate or attempt to relate well with your coworkers--especially management.
5. Share your vision of the company with your superior so that they see you have the organization at heart.
6. Do not become a slave to work, but show dedication while you are at work (forget the Facebooks and blogs while you are at work)
7. Less personal calls while you on duty (it shows irresponsibility and lack of respect for the person who has hired you.
8. Stay abreast on the market trends of the particular industry that you are in.
9. Network widely...make sure you establish enough friends in other companies who can serve as a positive referral or assistant in job seeking process
10. Always have a plan B...do not think that your job will always be there...think what else can I do if this job went up in flames?
11. Have a social life...your friends outside your job will be very helpful if you lose your job
12. Start a project or small business for supplemental income while you are earning--this may turn out to be your bread-n-butter if you are laid off and cannot find another position promptly.

So please do not sit comfortably and let destiny determine your future.
Do something about it!
