Current through 2016 New York Laws, Chapters 1 to 237
When probationary service is required upon promotion, the position formerly held by the person promoted shall be held open for him and shall not be filled, except on a temporary basis, pending completion of his probationary term.
Notwithstanding the foregoing or any other law or rule to the contrary, when a permanent appointment or promotion to a position in the competitive class is conditioned upon the completion of a term of training service or of a period of service in a designated trainee title, such service and the probationary term for such competitive position shall run concurrently.
