Direct deposit of paycheck question

[kerry]

Had to complete some 'new hire' paperwork since I'm teaching a couple of classes for my former employer. Included was a Direct Deposit Authorization for my paycheck. I was very surprised to read that it authorized my employer to both make deposits into my account and to withdraw from my account if necessary (as a result of a mistake). I am wondering if other people are signing such forms? A quick search of the internet revealed many forms which simply authorize deposits but a few forms which authorize both deposits and withdrawals, including the boilerplate form in Microsoft Office. It seems very unwise to me to sign such a form since it basically is giving your employer a blank check to access your account. Thoughts?
