You'd be surprised how much some employers care about those three minutes actually. I had one that didn't, but the job I had before this and my current job take being on time VERY seriously, and my current employer has let people go for repeat "three minute" offenses.

But they would at least say something to you before they fire you right? @TVwazhere

At my previous job yes, but my current job legally doesnt have to because it's part of the employment process and agreement (my manager does a good job of making it clear)

However I've found that if I have a valid reason and call it ahead of time, it's usually okay (though I am responsible for making the time up at some point later in the week) For example if I call in saying I'm stuck in traffic and I'll be fifteen minutes late, I'll have to maybe stay 15 minutes later that day.

My company isnt unreasonable, so long as you're reasonable about being transparent and trying your best to always be before, or on time.

Yeah, but my school gives 0 fucks, id rather stay at school another hour so i dont get iss, you also cant call ahead

If i get kicked out of rotc im going back to online school where i dont learn shit so fast because you get more holidays, work at your own pace and dont get fucked by retarded rules. @L.Lawliet

I feel for ya. I was glad to escape that BS when I entered college. Of course, some professors still dock points for lateness (even when you drop all A's in their classes).
