New Employer Succeeds Outgoing Employer. A New Employer who hires bargaining unit employees who were formerly employed by an Outgoing Employer at a building covered by this Agreement shall be responsible for accrued, but unused vacation benefits earned by those bargaining unit employees prior to the New Employer assuming the contract to perform janitorial services at the building. The Outgoing Employer shall not be responsible for accrued, but unused vacation benefits earned by any bargaining unit employees formerly employed by the Outgoing Employer who are hired by the New Employer at the building. The Outgoing Employer shall only be responsible for accrued, but unused vacation benefits earned by any bargaining unit employees formerly employed by the Outgoing Employer who are not hired by the New Employer at the building.
