This document discusses different types of pay plans beyond hourly and annual salary, including commission, piecework, and contract work. Commission pays a percentage of sales, so jobs like real estate agents and salespeople use it. Piecework pays per unit of production, common for factory workers. Contract work pays the agreed amount upon job completion, like for construction projects. Examples are provided for calculating earnings under commission and piecework plans. Advantages and disadvantages are listed for employees and employers of these alternative pay structures.
