Do you love your job? Don't want to even think about looking for a new position? Even if you're lucky enough to have a job you wouldn't ever consider quitting, you should be prepared to move on. Companies reorganize or need to lay-off workers for financial reasons, management changes, you could get a new boss who isn't as great to work for as your old supervisor, or your personal circumstances could change and you may need to seek employment.

A passive job search occurs when someone who is currently employed is open to hearing about new career opportunities, but does not actively seek out and apply to specific positions. That's a good model to follow because you will be prepared to job hunt at any given moment. If circumstances are such that it's time to job search, it's quick and easy to turn a passive job search into an active job search and you'll be good to go.

Passive job seekers who invest a little time in staying job search ready will save a lot of time (and stress) getting up to speed when they need to job search. Here are my top 10 tips for passive job seekers.

Be an Active LinkedIn User
Build a robust LinkedIn Profile including education, experience, volunteering, skills, certifications and associations, etc. Your LinkedIn Profile is the online version of your resume, so be sure to proofread it carefully. If you're new to LinkedIn, here's how to get started.

Once your Profile is set, connect with everyone you know. The operative word is "know" - don't connect with random people because they aren't going to be in a position to help you.

Join relevant LinkedIn Groups. There are job search groups, company groups, alumni groups, college groups, and networking groups. The Groups are good sources of networking contacts, job search advice, and job listings. Since you're not actively job searching, set the email notifications for each Group to a weekly digest so you aren't buried in messages.

Write Recommendations
Giving to get works every time. Write LinkedIn recommendations for some of your connections. In return, you'll get a recommendation back from at least some of the people you provide a reference for. Those recommendations show on your Profile and they are a reference in advance to a potential employer.

Tap into Social Networking
Don't stop with LinkedIn. The days when Facebook was only used for personal networking are gone. There are apps like BeKnown and BranchOut you can for professional networking on Facebook.

Set up Twitter and Google+ accounts, as well, and use them to expand your base of connections. Here's how to use social networking for career purposes:

Facebook
Google+
Twitter

The stronger your social presence, the more likely you are to be tapped by companies usingsocial recruiting to find candidates for employment.

Build a Career Network
You don't have to spend a lot of time networking, but do take the time to add connections to your network on a regular basis. The bigger your network, the more opportunities you'll have when you're job searching.

Stay Connected to Your Network
Don't build a network and forget about it. It's important for your connections to know you are there. Post status updates on Facebook, tweet now and then, post interesting links to your social networking pages.

If you have a blog that's appropriate for professional connections to read, feed it to your social networking pages. That way your pages will be current without you having to do much work.

Once a week, email or send a LinkedIn or Facebook message to five connections to ask how they are doing. Staying in touch reminds your connections of who you are and shows that you care about how they are doing. If you're interested and engaged, your contacts will be more likely to give you help if and when you need it.
