In this competitive job market, you have to stay on top of your game, so brushing up on your skills (or learning a few new ones) is essential to getting the job you want. I can't tell you how many people I know who have lost their jobs and decided to take a class at their local community college to learn a new skill. This is great, but they'll also be spending the next six to 12 weeks in a classroom every Thursday night while watching tons of job listings change from "Wanted" to "Filled."
So if you can afford a few classes, you can probably afford the $25 dollars a month (or $250 dollars a year) it costs to sign up with Lynda. Lynda provides an online classroom for you to refresh your skills in hundreds of subjects like video editing, Photoshop, web design, HTML, and Office just to name a few.
But the best part is, you have access to all of the courses Lynda offers, not just the one you are looking for. So you may go in for a course on Microsoft Office, but come out an expert on Office, Photoshop, and HTML. That should open up a few more job possibilities, right? I think it's quite a deal for the price, and if you've got the time (and the drive) to learn faster, it's only that much sooner that you can start sending out those updated resumes.
