Today networking has become an essential aspect of your job search. Even if you are well established in your job and have no plans of moving or advancing your career soon, networking has proven to be a valuable tool. Today, studies have shown that up to 80% of jobs are never advertised – they are filled by word of mouth. So it’s who you know and who knows you that matters. You must develop relationships and connections within your network to have more opportunities to advance your career.
