The time and a half by any company is not a requirement. Most companies give time and a half for SOME days (such as christmas and thanksgiving) but not necessarily, and the days they do that should be listed in your employee handbook. However, its just easier to ask your more veteran co-workers. If you work over 8 hours, any time over the 8 hours should be paid overtime, which in most companies, is time and a half. This would be different than holiday pay, which is optional by company.
As for breaks by law, in CA at least, if you work 5 or more hours, you are entitled to a no less than 30 minute off the clock break. However, if you work a total of 6 hours, you can opt out of taking that break. You also get a on the clock no less than 10 min break for every 4 hours (or majority) of work.
recap: If you work 4 hours, you get a 10 min on the clock break. If you work 5 hours, you get 1 off the clock 30 min break, and 1 on the clock 10 min break. If you work 6 hours or more, you get 1 off the clock 30 min break, and 2 on the clock 10 min break.
Break time is determined by state law. Go to your state's Department of Labor website to get information about when breaks are required, if any.
Federal overtime laws require that you be paid overtime (at one-and-a-half times your regular pay rate) for hours beyond 40 in a week. If you don't work more than 40 hours in the week, you're not entitled to overtime. There is no requirement for holidays off, or extra pay for working a holiday It's possible (though highly unlikely) that your state has a different law. Again, check your state's Department of Labor website for laws about holiday pay.
There is no holiday pay law in the USA.
If you worked the 4th of July, you would be paid straight time unless there is a company policy that says you get additional time or this was regular overtime hours.
PT employees do not get paid any OT or Holiday pay, and you are a PT employee
Workers don't have a lot of rights anymore - the republicans have destroyed them as much as they can. So you can speak to your union (oh right - you have no union). You could write to "Health, Education, Labor" - but they probably don't care.
