If you do not come to work during the furlough, you DO NOT get paid. period.
SSA payment center , one of the seven in the country, have been told to come in to work regardless of a furlough. In the past, everyone got paid EVEN if you did not come to work.
The TOP SALARIED people under the Regional Commisionner have been told NOT to come in.
I say DO NOT PAY ANYONE (except emergency or scheduled) if they do not come to work - save money.
