What is the ruling on working as a butcher in a shop that involves deceit and lying, and where the worker is forced to shave his beard, despite a severe need for the job?

Shaving the beard is permissible in cases of dire necessity, provided the need reaches a significant level, because its harm is personal.

As for consuming people's wealth unjustly, it is not permissible except in cases of dire necessity that would legitimize theft.

Deception, if it leads to a financial right, is permissible. However, if it results in harm to the buyer's health, there is no concession for it.
