...Personally for me when I have an employee quit I never try and retain them. See Ya Bye is my strategy. Plus your mind is already gone so retaining someone that has been looking ehhhh I pass on that.
While this is your right, as an employer, I respectfully disagree.
As an employee, you are a commodity that can be replaced at the drop of a hat. As such you are foolish not to "test the waters" from time to time to make sure you are being paid somewhere near the going rates because you need to watch out for YOU in the process.
While a company may not like the "water testing processes" it is what it is. Any employer who wants to keep quality staff either has to be sure they are already paying the going rate, or they are taking full advantage of employees who they are getting cheaply. This is dog eat dog stuff!
Long ago, employers looked out for employees. Employees used to give their working career's to the company which the company gave back well beyond a gold watch. Now-a-days, if they can figure out how to save benefits or can hire two for the price of one....you are more than likely living on borrowed time.
One more thing to remember for Fire...that is if you are being paid the "high bucks" and the economy turns...guess who gets to the cutting board the fastest?!
Lots of good advice on here but in reality salaries are posted all over the web today and with some research you can see where you are or where you are going by searching your job title. This will get you some basic idea to be sure you aren't being unreasonable for the job given, workload, region of the country, etc.
One last tidbit to consider and that is the extended time you will be on the road to the new job. Easy ride? Traffic jams? Bad weather? Extra fuel used, and wear on the old jalopy. It will add up and what looks really good now, might not be so good after 4 months of doing the drive.
