I have a large Russain Workforce, and would like to say a few words at the Christmas Party coming up.
"Thank You all for your hard work this year"
and
"Happy Christmas and a Happy New Year"
I will need phonetic help in what to say!
Many Thanks
"Спасибо всем за Вашу усердную работу в этом году" (Spasibo vsem za Vashu userdnuyu rabotu v etom godu).
"С Рождеством и с Новым годом" (S Rozhdestvom i s Novim Gogom).
PS. Please note that in Russia, New Year comes before Russian Orthodox Christmas, so you may want to reverse them:
"С Новым годом и с Рождеством" (S Novim Godom i s Rozhdestvom).
But, it is not necessary, they will understand either way.
Cheers.
