Singing builder

[UserOP]

We live in a terrace, house next door is empty and the landlord has builders round doing some minor work. I was so pleased not to hear any noise from the work as I work from home and it's my busiest time of year.

However, yesterday and today a new crew member has arrived and he sings at the top of his voice all day everyday. It's comical really, we've had everything from a crap opera voice to Robbie Williams.

As funny as it might be, it's really really distracting. I don't know why he's doing it, it's so loud as well! And there are other builders who seemingly ignore it

AIBU to go round and tell him to shut up?!

It'll be a real life musical.

Buy a BGT buzzer and buzz him when you feel it appropriate!

I would go and explain to him politely that you wfh and could he please not sing.

Write numbers from 1-10 on a4 sheets of paper and mark watch song when he finishes
Just ask him if he would keep his voice down a bit, he might not realise how loud he is.

Yes tell him he can have 1 hour per day for singing. The rest of the time he must be silent haha. Bear in mind if you shut him up they may just replace him with a radio.

These replies are making me grin. I was going to suggest earplugs.
Sorry OP it must be tiresome. When they stop for lunch, go round, be nice - say you work from home and can hear him singing very clearly but you have something you absolutely have to finish so could he please hum take it down a notch or two , thanks very much.
