I'm a little lost on some of this.
We have the situation that , after March 1, the Romanovs would be put on soldiers rations and each would receive 600 roubles per month from their personal estate. Did the Bolshevik state consider them soldiers, rather than prisoners? We know the answer to that one, I think.
Also, since the Bolsheviks claimed to be representing the workers' interests, why would they not have been paying the servants all along, and after the Romanovs were given this new "soldier' status? It seems the Bolshevik government was either throwing the servants into unemployment, or pressuring them to work at reduced pay, or for free. After all,allowing the Romanovs access to more of the interest from their personal estate would have also allowed them to pay the servants. The Bolshevik state would not have been bearing any burden, moral or financial , for the servants' continued service (employment).
Did the new Soviet state provide unemployment insurance, and if it did, would the servants have qualified?
