The developer shall guarantee the Commonwealth that he will employ workers who are available for all jobs for which they are qualified, acting on referrals of workers through established agencies and institutions of the Commonwealth. The specific jobs to be filled shall be established by the habilitator in conjunction with the developer, the Department of Public Welfare and Parklands Payback, Inc. Leases or other contractual arrangements shall enumerate specific job descriptions for jobs designated for the workers, and shall include a plan defining the developer-worker relationship to include hiring, firing, and other pertinent considerations such as funds for the habilitator's staff, workers' salaries or wages and rental provisions, and sharing of developer profits with the State. Failure to comply and maintain compliance with the provisions of this act as they involve the developer-worker relationship or other duties imposed upon the developer under this act shall constitute breach of lease with resulting penalties and/or cancellation, as set forth in the lease.
