I don't think a static breakdown will work for us as steam here. For two reasons.  Meetings comes in at anytime, if the major person that needs to be on meetings is on break, are we going to manage that with the client.. secondly, anything can come up and sla staff want to use their breaktime to attend to it. So it might be unplanned that am hour can be sufficient, instead of taking off for that period, I think their breaktime can be used for that.... I understand the structure you're putting in place but I think staff should be able to decide the time they are going in break daily once they resume at work.
