It is not up to your husband's boss to allow him to vote.
If he has to be to work before 7:00 he can go before or after work or during lunch and he can be late for any of that back to work. Or he can leave it 5:00 even if it's early to get in line. Once you are in line you are able to vote no matter what time you get in. People don't know the law allows them to vote. He could sue his boss and company.

If he works too far away from his precinct he just needs to leave work earlier
