24 Pa. Stat. § 5-524
The board of school directors of any school district, including merged or union districts, and any boards of school directors establishing any joint school or department, shall not close any school or department during the school term, unless such action shall advance the orderly development of attendance areas within an approved administrative unit and has been approved by the Department of Public Instruction. In the event a school board shall determine prior to the beginning of the next school term to close any school or department, sixty (60) days' notice, in writing, prior to the closing of any school or department, shall be given to all temporary professional and professional employes affected thereby, unless such action shall advance the orderly development of attendance areas within an approved administrative unit and has been approved by the Department of Public Instruction. Upon failure to give written notice of intention to close any school or department, the school district shall pay such employes their salaries until the end of the school year during which such schools or departments were closed.
Temporary professional or professional employes, whose positions are abolished as a result of the action of the board of school directors in closing a school or department, or reassigning pupils in its effort to consummate partially or wholly the orderly development of approved administrative and attendance areas, may not be suspended until the end of the school year if such action is taken during the school year or later than sixty (60) days prior to the opening of the next school term.
The payment of salary to any temporary professional or professional employe shall be discontinued immediately, if such employe obtains other employment which, in the judgment of the board of school directors, could not have been obtained or held if such school or department had not been closed: Provided, however, That if the salary in the new position is less than the salary the professional employe would have received had he remained in the employment of the school district, the school district shall be liable for the difference.
