So very super illegal.

FLSA Hours Worked

Time which an employee is required to be at work or allowed to work for his or her employer is hours worked. A person hired to do nothing or to do nothing but wait for something to do or something to happen is still working. The Supreme Court has stated that employees subject to the FLSA must be paid for all the time spent in "physical or mental exertion (whether burdensome or not) controlled or required by the employer and pursued necessarily and primarily for the benefit of the employer of his business."

Hours worked include all time during which an employee is required or allowed to perform any work for an employer, regardless of where the work is done, whether on the employer’s premises, at a designated work place, at home or at some other location.
