I work in a job where we occasionally work with different people from various areas, sometimes we can work with someone once then not see them again for weeks.
Anyway, I worked with a male before around 10 years older. We're required to have all colleagues' numbers to arrange meeting times.
I worked with him for around an hour as required, he seemed pleasant. Asked me if I were married but I thought it was just chit chat.
I arrived home and an hour ago I received a text saying 'Got any single friends for me? ;) '
I haven't replied. Not sure whether to ignore/reply/report to HR?
Unfortunately not the first time I've had things like this. It's out of order. My reply would be telling him it's completely inappropriate.
