If you haven't already done so, it may be time to organize your job search and networking efforts, even if you are currently working. Remember, if you wait until you are unemployed to start your networking, you have waited too long.
Changing jobs numerous times is part of the job-market landscape for the foreseeable future. Those entering the job market today will likely have 10 to 12 jobs and three or four different career fields, so changing jobs is inevitable for most.
A good source for organizing and carrying out your networking efforts is LinkedIn. Many employers will check your LinkedIn profile even before asking you for an interview. Some will Google your name to see what you have posted, and where. If you haven't already done so, it may be wise to Google your own name to see what a potential employer may find.
