rainbowbreeze hi, so you have a realistic expectation that the social workers will take up references fairly soon after you give the details and can do this once you have been in your job six months?
I agree it is hard you need to tell the boss your plans in a way that you would not if you were having a child a different route.
I think I'd just take a very matter of fact approach. That's what I did.
It's your right to engage with the process to have a child, have adoption leave and to go back to your job afterwards (if this is your choice). So just say your plans in a very matter of fact way, don't be apologetic or try and join the dots of what this will means in terms of adoption leave or return to work etc.
They only need to know now because this is your plan and they will be contacted. Share as much information as you wish, remembering that you cannot take back information (if you later wish you had not said so much).
As others have said help them to see the time line as most likely a long time. If you are fortunate enough to fly through the process and be matched quickly then it will be fabulous for you and the end result for your boss will be pretty much the same! Your boss will need to allow you time off for adoption leave (by law, if you are the one to stay off work with your child) and you will have the right to return after adoption leave, assuming you want to.
It may help to read up on the law so you feel empowered and not like you are inconveniencing them at all.
When I told my boss I was getting married he looked flustered and said "All my staff are leaving me!" Or words to that affect. It was a mean thing to say and took the sparkle off my announcement. I am not even sure I commented on it at the time.
Now almost 20 years later I would certainly point out that the normal phrase would be "How wonderful for you, Congratulations" not "All my staff are leaving me!" But he was kind of right, I did leave (six months later) and I didn't really care what his thoughts on my life were!
But do whatever gets you through the meeting!
