>Congress is the other branch of government and has no power or authority here.

The judiciary is the other other branch of government and absolutely has power and authority here if laws or contractual agreements (e.g., requirements to fire for cause) are being violated.

The President isn't an absolute monarch, even within the Executive Branch.

>Contacting representatives and senators would be a waste of time.

Aside from formal legal power, Congressional Reps and Senators can apply pressure to the President to change his policies, which they will do if enough of their constituents express their anger at these actions.
