* You may very well be more productive on a quiet train than a noisy office
* Inconsistent WiFi coverage could let you focus on work instead of video conferencing meetings
* Arriving late means you don’t have to stay long - not your fault the train was delayed, after all!
Your employer gets the badge data showing you technically showed up, you have the receipts on why you were late, and you get a partial or full refund on the delayed train fare for good measure.
