Google already has some tools to help you find a job, but there’s been a missing ingredient: salaries. How do you know whether or not it’s worth pursuing a new role short of visiting another website? You shouldn’t have to worry much longer. Google is adding a suite of new job search tools, most notably salary info. In many cases, Google will display estimated salary ranges plucked from multiple sources (including Glassdoor, LinkedIn and PayScale) whether or not the listing itself mentions pay. If a position represents a big raise, you’ll know very quickly.

I think if you already have job you need to know the salary why waste the time of HR and you if the job salary is not what you are looking for at the end of the day.
