You're free to quit and work somewhere else.
Seriously, the whining about increase in wages is getting a little ridiculous on this forum. I'm sure there was someone bitching about newbies getting the rate you got when you were hired, and so on all the way back to 1962. One of the things you sacrifice with longevity at any company on the planet is wages that keep up with starting wages year over year. Starting wages generally outpace merit & COL increases across the board, with companies doing market adjustments periodically to bring exisitng employees up to current rates (if your company doesn't completely suck, that is). That is what Target is doing here, though they're actually paying above market wages for regular retail.
There are usually tradeoffs with longevity in the form of benefits and job security and other things, but if you decide those tradeoffs are no longer acceptable, then quit and find a new job. That's how it works.
