Does anyone here work at Hannaford, Shaws, Target or anywhere else related?

I am a stay at home mom and my husband works a very good job. We just recently purchased a bigger home to accommodate our growing family. I need to get a part time job to help with the difference in our payments. Does anyone here work at the above jobs listed? How flexible are they? Would they reject my application because I would request mother's hours due to my husband's schedule? I would also request that I have every other weekend also due to my husband's schedule. I am so nervous about this!
