That would take at least six weeks to a month, and if you didn't have cause, forget it. Once they get through their probationary period of at most six months or so and become a permanent employee you can't fire them without cause. You can make them redundant, but then you have to pay redundancy (the statutory rate was recently increased on that) depending on length of service and god help you if they catch you filling their job within a year - it's suing time again.
What do they make you do in Germany? Sacrifice goats to the horned god? Swim across a lake of sauerkraut?
