In the US, where I assume a lot of the griping comes from, election day is not a national holiday, nor is it on a weekend (in fact, by law it is defined as "the Tuesday next after the first Monday in November"), and even though it is acknowledged as an important civic duty, only about half of the states have laws on the books that require employers provide time off to vote. There are no federal laws to that effect, so it's left entirely to states to decide.
