Would you give a different answer if you were not actively looking vs looking?
What are some other ways at establishing "market value"? Having used Glassdoor.com, how accurate is this?
If you want more money you can talk to your manager but other then that, you just need to get another job. It sucks but that is reality.
The raise-by-counter-offer strategy rarely pays off. You may get your raise but only until they can find someone to replace you.
Also, it seems like it would be make sense to deny an offer/opportunity if it's less than what you're currently making and/or vesting value.
I do agree that the counter offer strategy is not always a guaranteed win - I was more curious about people using this as a way to find out their "market value" (what someone is willing to pay/offer you)
Also, if that were the case, it would mean that:
* I under-valued, or under-negotiated my current compensation
* The current company doesn't value my skill set (either due to non-optimal performance or company structure)
