Labor Laws, do they apply in this situation?

Ok so, My week started on Wednesday September 26th and went through all the way to Wednesday October 3rd. Without any days off, I accumulated the hours I worked and it came up to be 52 hours. Anyways, I wasn't payed overtime because they said that I didn't work a 40 hour week since Monday you start out "fresh", is this right? Can they really do that?

For most companies a week is Sunday to Saturday or Monday to Sunday. So, sadly, yes, this is perfectly legal if that is the system your work is using. The work week is set up, and not just any 7 day period of time that you are working. Sorry!

Sorry but yes, If your company has defined work weeks they can start over

Most pay periods run from Sun - Sat or Mon - Sun.
Therefore, If you did not work 40 hrs during the standard pay period, you do not qualify for overtime. The pay period is standard for all employees in the company. It does not vary from employee to employee based on what days they were put on the schedule to work.

Absolutely. Every work week has a beginning and an end. If your employer starts their week on Monday, you worked 5 days last week and three days, so far, this week.

Most work weeks reset hours on a Monday.

You may also have in contract that you can only work an allotted number of hours per pay period before overtime applies. This means that you can technically work 80 hours over a 7 days stretch and still not get over time. it is a pain in the ***, however completely legal.

You need to check on your Labour Laws, and on any contract you have signed. Also which country are you in? They differ so much. That sound grossly unfair.

the EMPLOYER has the right to set the work week, and you cannot change it. Whatever the work week is, you are stuck with it.

Yes, they can. But they can't schedule you to work seven straight days a week, which is illegal, unless they call you in on your days off and you agree to come in and work. I wouldn't complain too much though because they can fire you for no reason within your first three months.

I believe they can do that. but it might depend on your state. What state are you in?

Yes they can because you can work 10 days straight and 5 at the end of one week and 5 at the start of an other. It is all legal for them. Sorry to agree with the man.
