Unless there is some contractual or union prohibition, I see no problem with the employer having you multi-task during your day. If you are working more than 40 hours per week you should get overtime.
The above answer, and any follow up comments or emails is for informational purposes only and not meant as legal advice.
This is the type of problem that only a union can try to solve. You and your coworkers need to look into union organizing. Hiring a lawyer will not solve your complaint.
You should be getting overtime for all work over 40 in a week. If you are working on a prevailing wage job you should get overtime after 8 hours of work in any day.
PLEASE READ THIS DISCLAIMER * I very much like to offer my advice and guidance to those in need. It is why I became a lawyer. However, please note that I have not been engaged to be your lawyer so my advice is general in nature. Certainly, if you would like, please feel free to email or call me to further discuss the particulars of your situation (as many times it is not a good idea to provide a lot of information about your case on a public forum). * Hacker Murphy serves clients throughout New York State (including New York City and Long Island). *
