I don’t know how long it takes you to close the store, but I’d recommend starting the process earlier so you can be out by 12:30 and make the last train. This is what a pretty much everyone has to do.

Check local bus schedules as well, some might run a little later.

Several years ago, we did experiment with late-night T and Bus Service but there wasn’t enough demand to justify it. There was big backlash when they removed it, particularly from workers like yourself and hospital workers. Maybe it’ll come back with a new GM, I think extending T service by just an hour would be really useful.

Biking is fine, people do bike in the winter. Get special tires for the snow and ice tho.

Otherwise, if you don’t have a car - your options are Uber or walk. Or request a different shift.
