Yes, ask about vacation and sick leave policies, you should probably get 2 weeks vacation but that could not be until after a year and there might be 401K and other plans then too. You do get unemployment, which is very expensive; if you are self-employed you have to pay it all but your company pays half or more when you work and probably some sort of disability. The taxes, tips, and gratuities to be allowed to hire you costs them money. The basic formula is that an employee costs the company about twice what his salary is to employ; with sick, vacation, and holidays, help with insurances (some or all health in the old days), etc.

Salaried people do not get overtime, just their salary. That is one reason they probably have the job as hourly; they know it requires a lot of time and/or don't want to have to hire another person to help you (as, even at $8/hr. or something for an assistant, they'd be paying $16 actually for tax, tips, and gratuities of hiring the person). After a year or so you might want to talk them into hiring someone part-time to help you; use your wages/hrs. to show how it would not cost them more or much more and you would get a built in person to "supervise" which would look wonderful on your resume (if you could manage without overtime for six months to a year and/or get another couple dollars an hour or more schooling paid for (even just a supervisory course or something).

It's hard when you are a whole department yourself. I had to run a non-profit and my first chore, which were overdue, was the payroll taxes which I'd never done before! Fortunately I had had a couple semesters of accounting and I had the contact number of the person who'd had the job before me, the first person to have the job at all, but she was out-of-state. I called and talked to her and she was vague and clueless (probably why she'd quit the job) so then I realized I was truly on my own and could do whatever I wanted That was $8 an hour but in the mid-90's.
