Call Center Agents not getting any leave on Election Day

Tomorrow is a non-working holiday which is usually a working day for call center employees. If I was still in the BPO industry, this will not be a concern for me since the voting hours are morning till the afternoon and my shift starts at night. Coming from a Sat Sun restday, no worries. But what about those who have shifts on a Sunday night? Can they still vote after their shifts? Just a little sleep sacrifice since they still need to go to work on a Monday night. Maybe the main concern here are those working on a technical account like Verizon or something with shifts of 7am to 4 pm. Clearly, how can they vote? The management especially the workforce should have planned this so that their employees on that shift can still make it to their respective precinct.
