New Yorkers who take the subway on Sundays may not know the name Jose LaSalle, but they might have seen him around in his orange safety vest. Mr. LaSalle, 55, is the deputy chief of weekend service diversions and coordination for the Metropolitan Transportation Authority, which oversees the city’s subways and buses. That makes him the person responsible for troubleshooting and handling customer complaints at stations when there are delays and service disruptions. Every Sunday that I’m not on vacation, I wake up at 5:30 a.m. As soon as I wake up, I have this habit of checking Slack. I’m checking for service diversions, things I can prep for.
