Disadvantages of trade unions

• they sometimes encourage inefficiency by forcing employers to employ or retain unnecessarily large numbers of employees.
• through force, trade unions can coerce the workers to support the "unions" opinion by joining strikes which affect production.
• a powerful union of workers in a particular industry can through unreasonable demand for wages not only secure higher wages but may induce workers in other industries to make similar demands though unreasonable.
• through political leanings, the workers can be misguided to achieve the trade unionists political motives.
