Okay here goes, I do overtime at night in my work. We had a new boss join us about 5 months ago. He's 40 years old and I'm 30. We chat away often and we have a laugh, however he always asks how my bf is and what I've been upto and he recently was chatting about his partner also. He asks me things like how much do I make a month, what's my favourite pizza what do I do at weekends, do I go out. He left his wife for another woman who he is currently with, I'm certain he met her at his work as she works for the exact same company in his old store. I work dayshift normally but there's always overtime on nights and he likes to have me in because I'm a great worker. Anyway last night he asked me for my personal number so he could contact me about overtime. Is this weird? I see him most mornings when I start my dayshift hours and he's finishing nightshift so he could ask me then like he has been doing. Also my sister works nightshift 4 nights a week and we stay together in the same house so if he really needed to get a hold of me he could just ask my sister to pass the message on ( he knows my sister wouldn't mind ) he also hasn't mentioned to my sister that he has my personal number to contact me and I really don't think he has anyone else number. Am I overthinking or is there something in it.
