I absolutely do think that employers should only be able to ask how long you worked somewhere and not how long you worked there. Sites like linked in should give you the ability to only publicize tenure and not approximate dates of employment.

I'm employed but but an issue like this is worrying for other reasons like the decision to take a break from the labor market and travel. What if I want to dip in my savings and travel for a year. I'm unemployed for greater than 6 months in such a situation but voluntarily so.
