Various reports have stated that because of the way Russia does meat assaults it is more like 990 dead and 110 wounded. There is of course no way to know for sure (at least not public information, who knows what classifed data shows).
There are also an unknown number of POWs and surrenders that are not in the 1100 number.
In the cases where I've been asked to do things like this it was instead of my regular work, not on top of it. US labor laws are tricky, but in general they need to assign you an amount of work that can be done in a reasonable amount of time. (contact a lawyer for details)
