Is it normal call into work because i'm just too tired.

We all do sometimes. But you might need to get more sleep, because they won't like it if you do it too often. Get more zzzzzz's man.

sometimes depression makes you tired. sometimes jobs depress you. sometimes jobs make you tired. sometimes you're just a lazy asshole with no work ethic. who knows!

That usually is a symptom for another problem--that you don't like your job.

I once had a job where it was acceptible to do this. We called them "mental health" days.

It depends on why you're tired.

If you're tired from goofing off or playing then it's your own damn fault. :-)

I do it because I'm lazy.

A guy at work told me last week that he almost called in sick because his wife was tired. If you knew the back-story, you be amazed that I didn't roll my eyes.

Yeah honestly who hasn't done this. Just try not to make a habit of it.

Not sure if it is "normal" but i have definately done it before... Its probably due to having a stressful job

I would fire you! That's pretty worthless.
