For decades people have blamed being late to work because of the subway but without proof it was hard to believe them. Now if there is a delay on the system within two weeks a note will be sent in the mail.
Passengers have to call in the late notes to the NYC Transit. The NYC Transit then verifies the date and time of the delay sending an official note within a week or two. The system has been around for some time with 34,000 notes sent out a year.
The NYC Transit is working to have this process go online so the excuse letters can be emailed.
