I have signed a contract with a German company, and one of the clauses says that if I am unable to start working for them, in the case of intentionally resigning, then they would charge me one month of paid salary (5000 EUR).
I didn't even work one day for them, and they only have my emails and physical address in Argentina, but they don't have anything else.
I have signed the contract, but meanwhile I found another job, in Germany too. And I would like not to proceed with them.
Do I really need to pay them one month of salary? Is this something legal to have in a contract?
They have told me that if I don't pay, they will take legal steps.
Here is the clause:
"The employee shall pay a penalty for breaking the contract in the amount of the monthly salary, if he or she fails to take up the employment."
I just want to follow the law. How should I proceed?
