I'm going to put the blame on my manager about my forgetting to come to work.
Oh really? How are you gonna make it his fault?
I'll say he changed the schedule.
You shouldn't try and blame your boss if you knew the schedule. You could get fired.
Nah. I bet he didn't think he made a mistake.
If he finds out you're lying you could get into a lot of trouble though. Why not just come clean?
