Can my job do this??

So I started a little part time job to help my hubby with bills..

I accepted a 32 hour position They had available.

Anyways yesterday was supposed to be my first pay day yet the mail didn't run whatever...

Well when I filled out my app I put I can't work weekends cause my hubby works a 48 shift all weekend he's a emt.

So anyways are the supposed to provide you the days you said on your app you can't work?

What do I do she has me scheduled this weekend and I have no baby sitter if my hubby is working! And he makes way more than my 9. A hour so it's a loss if he calls off to let me work!! That's our real cunk of bill money

Ugh this is pissing me off all I wanted to do was help my family not have more problems.
