Is OTHER wrong in the post ? POST : I work in a public safety career, and as such I legally cannot leave my post until my relief comes in. The usual rule of thumb for people who work this job is "if you're not early, you are late". A few coworkers of mine were regularly showing up to work 5, 10 minutes late. I told my supervisor (didn't name any names, just gave a general note about the issues) and he sent out a memo to everyone reminding us to be on time.

Fast forward a month. I am 12 hours deep into my shift and 3 minutes before my relief is supposed to CLOCK IN, she calls into work saying she just got stuck in her driveway because of the snow. She lives about a mile away. She didn't show up to work until an HOUR later.

I felt really frustrated (what adult in the northeast doesn't know to leave earlier to adjust for bad weather) and sent another email to my supervisor, this time with an actual name of my coworker. 

Now she is mad and even "unfriended me" on facebook to punish me or something?? This woman is old enough to be my mom, AITA for wanting her to be held accountable for her actions??
