I have a full time work and because of corona I am kurz Arbeit. I find another work and I sign the contract and the contract did not state if is full time or teilzeit or mini job . And they did not write how many hour in a week or how days in a month.
They only write 11euro pro stunde.which means my work is not fixed hour or monthly payment.
My question should I terminate contract with my first work which is kurz Arbeit which my company is close . What can I do should I kundigt the work or not
