Yeah she likes you mate, to be any clearer she'd need to have landing lights on the bed sheets. Just ask her out, I'm pretty sure you aren't the first person to go on a date with a co-worker.
To be clear, when she said "you're up early on your day off" read that as "I woke up and checked your status on Whatsapp, I obviously like you, please ask me out".
Look at Hitch over here, clearly got women all sussed out as always
