Every Federal Government agency is different. Yours might be serious and on the ball while others are doing the bare minimum while sitting at home. Workers at the EEOC..... how much work are they doing at home? My guess minimal.
And for the goof offs they have two laptops on their desk. The Government issued work one and the goof off one used for porn, Amazon shopping, ebay, Facebook. Instagram and so on
I think my agency is a little more dedicated to meaningful work (CBP).
I do confess I have my personal computer fired up on another desk while I work, but thats so I can stream Rush and find out whats really going on...
