Asking a girl I work with out

Aight fellas, so there's this girl I work with. Now I really wanna ask this chick out but I have a few obstacles. Such as going to different schools and having slightly different work schedules so we don't get off at the same
Time. I've spoken to her a bit but obviously at work I don't get much time to get to know her.

My question is what should I do in this situation? Should I add her on Facebook?
Hlw could I get her number?

Any tips would be appreciated I'm not hell bent on getting this one I would really just like some advice never been. In a situation like this.

Get her number and then call her on the weekend. She's probably free then. When you call her, try to set up a casual date. Good luck.

Yeah it's just finding a good time is the problem dude

Yea add her on fb, give it a day or so and just ask her what shes doing this weekend
