Stress and Resiliency: Understanding the "Back to Work Blues"
                    
            Most Canadians enjoy a brief respite from  work during the holiday season. Many tack on a few vacation days to the  statutory holidays to create a prolonged break, perhaps to visit family or travel  to warmer climates. While this may maximize family time and allow the freedom  to participate in a wide variety of seasonal activities, returning to work  afterward can present a challenge. According to a recent English survey, 80  percent of employees return with signs of post-holiday tension (PHT), also  known as the "back to work blues."
The exact symptoms can vary from person to  person, but employees dealing with PHT will commonly feel exhausted, irritable,  and unmotivated. They may experience an apathy that prevents them from focusing  on their tasks, causing their minds to wander instead. PHT may even be  expressed through headaches and foul moods.
Transitioning back into the work routine  can seem overwhelming, especially when combined with the natural low that  typically follows a busy, celebratory time. Even employees who love their work  can experience difficulty returning after a break. To help you get back into  the flow, consider these tips:
1.  Show up to work ready and rested. Nothing will amplify the blues more than returning in a state of exhaustion or  disorganization. Get plenty of rest before your first day back, then organize  yourself and your workspace to be as efficient as possible.
2.  Be present. You may have thoroughly enjoyed the break, but it's now time to get back to  work. Set aside your holiday mindset and direct your energy and attention  toward your work instead.
3.  Create and prioritize a to-do list. Doing so can add structure to your work and enable you to more easily focus on  the tasks at hand. Include everyday tasks that you may not typically include on  a to-do list, as you may need the reminder until you get back into the swing of  things.
4.  Begin planning for your next break. Whether your next vacation is weeks or months away, starting to plan for it  will shift your focus from the break you just experienced toward the next one.  Even a long weekend on the horizon can provide a target to work toward.
5.  Define your goals. What are the next targets you are working toward? Determine what you are hoping  to accomplish and identify the steps that will get you there. Having  clearly-established goals can lift your spirits and provide some much needed  motivation when facing the blues.
By recognizing the potential of PHT and  taking steps to relieve it, you should settle back into your work routine  quickly and smoothly. If symptoms persist for more than a few weeks, however,  consult with a health professional or counsellor.
Holidays and vacations can provide a  much-needed break from the demands of the job, but they should not leave you  unable to fulfill your tasks. Instead, by taking steps to mitigate the back to  work blues, you can return renewed and reenergized, ready to take on whatever  comes your way.
