This time of year often calls for personal and professional reflection. It is a good time to show thanks and acknowledge your achievements over the past year. It is also good time to re-evaluate your employment situation.
Loyalty is certainly an admirable trait but if you are not willing to at least consider other jobs, you might be missing a real chance for career advancement. Of course the grass is not always greener elsewhere, but you will never know unless you are willing explore other options from time to time. There may not be such thing as the absolute perfect job, but you might be able to improve certain aspects of your career that are particularly important to you.
So ask yourself if you are just thankful to have survived another year on the job or if you have plateaued in your current employment? If so, it is an excellent time to consider a change because there is no better time for a job search. People are on the move in the first quarter of the year and businesses of have positions to fill so it is a perfect time to explore your options.
