The present invention relates to a method for operating a workstation and a workstation of an open ended rotor spinning machine. In the method, after intercross coiling a cylinder and changing an empty case, a spinning thread (7) fetched from a spinning rotor (26) is fixed to the empty case (10). The spinning thread is fixed at the empty case (10), when the rotor (26) is rotated at spinning rotor rotational speed (nL1, nL2) below operating speed (nB) during normal spinning operation. The spinning thread is fixed at the case, when thread withdrawal speed is below preset thread withdrawal speed (vL1, vL2) and rotational speed of the feeding roller (25) during the spinning operation.
