Trial Service Period An employee who has satisfactorily completed their probationary period and who is subsequently appointed to a position in another classification shall serve a twelve (12) month trial service period, in accordance with Section 10.1.3. 10.4.1 The trial service period shall provide the department with the opportunity to observe the employee's work and to train and aid the employee in adjustment to the position, and to revert such an employee whose work performance fails to meet required standards. 10.4.2 An employee who has been appointed from one classification to another classification within the same or different department and who fails to satisfactorily complete the trial service period shall be reverted to a vacant position within that department and classification from which the employee was appointed. 10.4.3 Where no such vacancy exists, such employee shall be given fifteen (15) calendar days' written notice prior to being placed on a Reversion Recall List for their former department and former classification and being removed from the payroll. 10.4.4 An employee’s trial service period may be extended up to three (3) additional months by written mutual agreement between the department, the employee and the Union, subject to approval by the Seattle Human Resources Director prior to expiration of the trial service period. 10.4.5 Employees who have been reverted during the trial service period shall not have the right to appeal the reversion. 10.4.6 The names of regular employees who have been reverted for purposes of re- employment in their former department shall be placed upon a Reversion Recall List for the same classification from which they were promoted or transferred for a period of one (1) year from the date of reversion. 10.4.7 If a vacancy is to be filled in a department and a valid Reversion Recall List for the classification for that vacancy contains the name(s) of eligible employees who have been removed from the payroll from that classification and from that department, such employees shall be reinstated in order of their length of service in that classification. The employee who has the most service in that classification shall be the first reinstated. 10.4.8 An employee whose name is on a Valid Reversion Recall List for a specific job classification who accepts employment with the City in that same job classification shall have their name removed from the Reversion Recall List. Refusal to accept placement from a Reversion Recall List to a position the same, or essentially the same, as that which the employee previously held shall cause an employee’s name to be removed from the Reversion Recall List, which shall terminate rights to reemployment under this Reversion Recall List provision. 10.4.9 An employee whose name is on a valid Reversion Recall List who accepts employment with the City in another class and/or department shall have their name removed from the Reversion Recall List. 10.4.10 A reverted employee shall be paid at the step of the range which the employee normally would have received had the employee not been appointed.
