Downsizing is the act of reducing the labor force of a company or organization, with usually multiple employees at once.Although, in some cases, other companies give their employees a new contract for part-time or freelance roles to cut back on employee benefits.Downsizing often occurs when a company is experiencing a great decline in revenue, and thus needs to cut costs.However, some companies downsize because of changes in leadership, realignment of business goals, low demand for product or service, or unproductive departments.
