The sky is not falling for those government employed workers yet. First the private sector will degrade and government will try to squeeze every last cent out of it to pay the public sector workers. So when that dries up, then you can expect trouble. But this process can last for some time, it doesn't usually happen overnight. I know that there are major sanctions and West is trying to tank Russian economy, but don't expect to see public sector workers on the streets just yet.

If they don't have that wage, how do they eat?

If they have that wage, how do they eat? Russia is not self-sufficient. Going it alone means people will starve to death.

They won't starve to death in March, but it won't be long before buffers are empty. There is a window to do something about it.
