Missed my second day of work?

I'll be brutally honest. My iPhone alarm didn't go off this morning because it's dumb as ****. But yeah, I overslept and today would have been my second day. Am I going to be fired? I don't even feel like making excuses to my boss. It was just a real case of oversleeping. I actually like this job very much. So is there still hope for me if I just go in and tell the truth?

Yes, just tell the truths and explain the situation to him. Make sure he knows how much you love the job and make sure he knows it would never happen again…

Did you just decide to not go to work as you overslept or did you go into work late?

Most workplaces would fire you for being unreliable. Will yours? We can't answer.

Doesn't look good as an employee that can be relied on
if you need the job hopefully you won't get fired

So why didn't you go in quickly the moment you did wake up. You have used the faulty alarm as am excuse to miss a whole day. It would look better if you had hurried in and been very apologetic today, rather than skipping the whole day.
