If there is one thing that you can rely on it is that change is inevitable. Technology and industry expectations and standards are always changing and the best way to future proof yourself as an employee is to always be learning new skills and honing the skills you have with the most up to date information.
There are a variety of ways that you can keep your skills sharp. The internet provides endless opportunities to research topics related to your field, there are numerous sites dedicated solely to teaching you about nearly anything you want, and even YouTube offers hand-on video instructions to anything you can think of.
Check with your Human Resources department to see if they offer in house training or are organizing group sessions for related skills. Having an employee with new and up to date skills is an asset for any company so many of them will even offer to reimburse employees for a portion or even all training costs.
