I would like to comment, but there is one piece of information that is missing and this creates an obstacle to any detailed and rational analysis. The unanswered question is this: Since only 1/3 of the tellers making $11.99/hour require assistance what is the difference between the 2/3 of tellers who can make it on their own and the 1/3 who cannot? If they are all making the same wage, the wage alone cannot possibly be the problem. Although I cannot say with certainty what the problems are, I would suggest two possibilities: (1) part-time employment and (2) employees with more dependent children than their wages will support.
I've always known that many tellers work part time, and there are many links that will verify this is true. Here is one such link:
These days about 27 percent of bank tellers work part-time, according to the BLS. And their median hourly wage was $11.59 in 2010, the most recent year for which BLS has data. The average Wall Streeter earned $362,950 in 2010.

It appears there is a rather close correlation between the number of part-time employees and those who need government assistance. But there is also an issue regarding the number of dependents each teller must support. According to one site:
Researchers say taxpayers are doling out nearly $900 million a year to supplement the wages of bank tellers, which amounts to a public subsidy for multibillion-dollar banks. The workers collect $105 million in food stamps, $250 million through the earned income tax credit and $534 million by way of Medicaid and the Childrens Health Insurance Program, according to the University of California at Berkeleys Labor Center.

Since the total Earned Income Tax Credit (EITC) paid to the tellers is $250 million we can estimate the number of tellers who have one or more children. According to the IRS EITC tables for 2010, those earning $21,400 per year are entitled to $2,255 for one child, $3,988 for 2 children, and $4,618 for 3 or more children. Thus the range is somewhere between a minimum of 54,136 tellers ($250 divided by $4,618) and a maximum of 110,865 ($250 million divided by $2,255). It is more likely that the average payout is close to $3,988 for 2 children which means the actual number of those receiving EITC is close to 62,688 ($250 million divided by $3,988). The EITC tables are at the following link:

According the the U.S. Bureau of Labor Statistics, there were 560,00 bank tellers in the USA in 2010. Since only 187,000 (1/3 of the 560,00 tellers) need assistance and part-time work accounts for 151,200 of these employees (27% of the total), the only task is to account for the remaining 6% or so (remember, I am not attempting to be precise) which would be 33,600 workers. We have already established that close to 62,000 of the employees have, on average, two dependent children and some of these are no doubt full-time employees so we have closed if not eliminated - the gap.
Here is the link showing the number of tellers in the USA:

Here is an interesting analysis: If the 187,000 people who needed public assistance were all part-timers and most part-timers work 20-30 hours a week, the total government outlay of $900 million would be unnecessary if each worker worked an extra 7.7 hours per week. Here's the math: $900 million divided by 187,00 workers equals $4,813 per year; at $11.99 an hour each worker would have to work an additional 401 hours per year or around 7.7 hours per week.
Unfortunately, There are generally two reasons for part-time work. The first has to do with government regulations and the second has to do with legitimate business needs. Many businesses cannot survive without part-time workers who can assist during periods of high demand but who are not needed at any other time. From what I've read, many bank tellers are in this very position.
My final thoughts. Many tellers don't need an hourly wage increase, but instead just need more hours. Given the nature of the banking business this may not be possible. Also a number of tellers, even those working full time, are not making enough to support 2 or 3 children. However, wages and salaries are not determined by the needs of the most needy, but rather the contribution one makes to the organization. Sometimes the only workable solution is to change jobs or get a second part-time job.
I wish things were different, but I don't know how to make them so.
