Did your client pay for child care at that time?

Have you used the IRS resources?

"You may be able to claim the child and dependent care credit if you paid expenses for the care of a qualifying individual to enable you (and your spouse, if filing a joint return) to work or actively look for work."

You hit the nail on the head Lisa... Some of them probably made more money on unemployment than they did when they worked, therefore they had little "incentive" to actually try to find a job... just my opinion
