People will still need to work on election day, but the amendment could specify a minimum amount of time be available to participate in the election.
(still, early voting makes more sense to me than that)
Friday, January 1: New Year’s Day
Monday, January 18: Birthday of Martin Luther King, Jr.
Monday, February 15: Washington’s Birthday (aka Presidents Day)
Monday, May 30: Memorial Day
Monday, July 4: Independence Day (aka Fourth of July)
Monday, September 5: Labor Day
Monday, October 10: Columbus Day
Friday, November 11: Veterans Day
Thursday, November 24: Thanksgiving Day
Monday, December 26: Christmas Day*
Even growing up I had (public) school on Columbus Day.
Service workers work on almost all of them. Even the once sacred Thanksgiving isn't a day off for many retail employees anymore. Where I worked year ago they brought in low paid part time workers on holidays to cover for the full timers (who had benefits) who had the day off.
