<human>: Okay so I started a new job about a month ago and there's this really cute girl that works there with me. We are both new because it's seasonal. We've talked a little and she's really nice but we haven't talked like, a lot.

Well my manager sent a mass text out to all the employees asking if someone wanted to come in for a couple hours, and she responded saying that she could come in, blah blah. Well I thought it'd be a great idea to text her from that. 

All I said was, "Hey! I know this is random but are you working on Friday?" No smiley faces or anything.

Is this crossing the line? I REALLY don't want to come off as weird or too strong because even if we never talk again, we work very closely to each other.

Can you condense the text into three sentences or less?
<bot>: Texted a co-worker without her giving me her number. Asked is she worked on Friday. Is this weird?
