With no wage raise in years - would you turn down a bonus?
Who'd turn down free money, right?
But many employers, though not having offered a raise in years, have offered some extra income that not nearly all of their employees make use of.
If the employee makes a contribution to their retirement plan, many employers offer to pay something also, often 50% of that amount, up to a certrain maximum, e.g. 6% of the employee's wage.
Quite a large number of employees don't make full use of such an offer, with a substantial percentage of their workforce making no use of it at all.
See my message on this topic over on the Kitchen Table forum. And, quite liely (dang computer - that was supposed to be "likely"), discussion, as that's a busy forum.
With regard to that error ... do you figure that we should "finger" the fingers??
