Hello Elaine,
Your question is not that easy to answer.
If your net income (during short-time work) is sufficient to cover your rent, your other payment obligations, as well as the new loan installment, there is nothing against granting a loan during short-time work.
However, if this results in a liquidity shortfall, you will not receive a loan.
There may be one exception: if the short-time work is temporary for you and your employer confirms that the previous net salary will flow again afterwards!
Best regards
