Back in my Big Agency days, one of my colleagues claimed that his extended absences for "client meetings" helped him save his job, despite the usual agency churn. "If they can't find you, they can't fire you," he said. I guess that's not true any more in these Crackberry times. Now, a more appropriate statement might be, "If they can't find you, they can't hire you." Even with the pervasiveness of social media, many folks refuse to venture in. Check out a possible hire on Google, and he or she may as well be wearing a Cloak of Invisibility.
Some thoughts: LinkedIn is a great place to start building a network of friends, colleagues and business acquaintances. You won't be best buddies with all of the folks in your LinkedIn contacts list, but they sure can help you with introductions to possible employers, and recommendations on your work. It's fun and it's free. Other similar sites include Plaxo and Naymz.
Get on Facebook with a profile, a photo and start inviting your friends. Soon enough, you'll be friends with some people you might just vaguely remember, but it's all good. You don't have to accept all invitations. Just remember, everyone can see this, so don't include photos with groups of drunken friends at a club, perhaps. Better to be businesslike than put people off with a show of tattoos and questionable wardrobe choices.
There are also some very informative sites out there with tips for job seekers as well as articles on PR tactics, tools and campaigns. Check out www.ragan.com and sign up for free. If you're a PRSA member, there are lots of resources available to you, including free webinars at www.prsa.org. It's important to know what the traditional and social media issues are out there, when your potential employer asks.
