You can tell them whatever you want, and they can fire you if they want. But to keep your job, you have to work how many days they want you to work; you can't work more than they want, and if you work less than they want, they might fire you.
Yes, and they'll either say ok, that's just what we need, or else say thanks for coming in, but we need someone for more, or less, than that. Or they might hire you, then schedule you for either more or less hours than you asked for.
