Anybody here familiar with the piece rate pay?

Apparently, our company/bosses have decided to pay us differently. Now I don't know if this has been implemented for the entire service department or only a batch of us. We are on hourly rate pay while other techs or repair (master) techs are still on flat rate system. We used to work 40 hours a week but I believe it will be 44 hrs from now on due to new schedule & timing. Four days a week only. I get two days off. I don't work on Sundays. The new pay is as follows - (going to keep it simple) if you achieve at least 75% of your clock hours (30 hrs or now 33 hrs) you shall get paid $15. If you do not, then you are at minimum wage $7.25. Keep in mind this means 'wrenching/labor hours' as your clock hours. There have been other changes as well. There are now five teams and each team shall have three techs working that can handle two to more cars at a time. I lead my team apparently and if my team earn at least 10+ hours combined then we can safely assume that we can make that $15/hr over the course of one week. For example, lets say my teams makes 8.70 hrs on Mon, 10.30 hrs on Tue, 9.80 hrs on Wed, 11.20 hrs on Thu, then we add those hours and get 40 hours for week one. This means we have safely made over 75% of our clock time and shall get paid $15/hr. One thing I need to clarify is whether we are still on the hourly rate or is it like the flat rate system. After 30/33 hrs do you get paid $15 hourly or $15 times the amount of hours you earn for the rest of the week?



The only problem is that as long as there's work then there's potential. Otherwise, not.



Hence, asking if you any of you have experience in this system and what has been your view/opinion about it?
