In McLane v. Atlanta Market &c. Co., 225 Ga. App. 818, 822 (1) (486 S.E.2d 30) (1997) a real estate agent was entitled to commissions from her broker when tenants to whom the agent had rented office space entered into amendments to their leases through which they occupied additional square footage. The Court held that the agent's right to commissions was not defeated by reason of the fact that the lease amendments were executed after her at-will employment was terminated. The basis for this holding was that the agent had earned the commissions based on services she had rendered before her employment ended (i.e., past services).
