Paraphrase this statement - Among others, the noted difference is their working conditions, hours of work, and pay rates, including the categories of their positions and employment status. As stated by the petitioner corporation in its position paper, due to the nature of the business in which its livestock-agro division is engaged very few of its employees in the division are permanent, the overwhelming majority of which are seasonal and casual and not regular employees. They have very little in common with the employees of the supermarkets and cinemas. To lump all the employees of the petitioner in its integrated business concerns cannot result in an efficacious bargaining unit comprised of constituents enjoying a community or mutuality of interest. Undeniably, the rank-and-file employees of the livestock-agro division fully constitute a bargaining unit that satisfies both requirements of classification according to employment status and the substantial similarity of work and duties which will ultimately assure its members the exercise of their collective bargaining rights
