That's a fur jump.
A postal working today makes a base wage of say $14.00 over minimum wage, or about $21 per hour(a figure which is too low, but just for example purposes).
Next, a hike in the minimum wage of $1.50 takes place. That means the new base wage for the postal or government worker's next paycheck and pension accruals just rose from $21 per hour, to $22.50.
Get it now?
