Exactly, if anything this strike is timed to do the least damage to the general public relative to the amount of impact it has on the business. The election has already been decided, we're just waiting to tally the votes. Most people have already decided if they're going to vote and if so who for.
If they had striked last week or the week before they'd have been accused of election interference. Striking this week hurts the Times because they run the risk of losing traffic from people trying to see results, but it doesn't impact the results at all. It's the best possible time to strike this year.
