The MTA cares about its passengers. In fact, it cares so much that it will provide you with a note to present to your asshole boss if train service is ever delayed.
The New York Times says that the agency has given out over 250,000 notes since June 2010. The notes that look something like this:
There was a disruption in service, specifically signal trouble, sick customer, brakes in emergency and track circuit failure, which caused massive service delays, reroutes and/or trains to be discharged on the 1, 2, 3, 4, 5, 6, 7, A, B, C, D, F, J, L, M, N, Q and R lines,” one recent response read, in part. “As a result, any one delay lasted up to 82 minutes.
That should satisfy your boss, but don't abuse the excuse. You don't want to end up looking like the delinquent employee who cries wolf (or "late") every week.
