As of December 31, 2023, on a consolidated basis, we had 9,229 employees, of which 71.9% were unionized. In December 2023, a new collective bargaining agreement was signed with the main unions, which will become effective in September 2024 and expire in December 2027. We generally apply the terms of our collective bargaining agreement to unionized and non-unionized employees. We have traditionally had good relations with our employees and their unions, but we cannot assure you that in the future, a strengthening of cross-industry labor movements will not materially and adversely affect our business, financial condition or results of operations.
A new labor reform was approved by Congress in April 2023, which, among other reforms, shortened the work week from 45 hours to 40 hours. Additionally, the minimum wage formerly set at Ch$350,000/month (U.S.$400/month) in 2022 has been gradually increased and will reach Ch$500,000/month (U.S.$572/month) as of July 1, 2024. At Santander Chile, the weekly working hours agreed under the new collective bargaining agreement were set at 40 hours and the minimum wage at the Bank was set at Ch$1,030,000 as of June 2024 (U.S.$1,178/month). Despite this, we cannot assure that the new labor reform, or any further increases to the minimum wage, will not have material impact on our expenses.
In addition, a bill was introduced to Congress to modify the terms of the "gratificación legal," which consists of an annual participation to employees of a company's profit. The new bill being discussed seeks to modify the Labor Code regarding the participation of workers in the profits of companies. The new bill proposes to modify the Labor Code to increase the gratificación legal distributed to employees and change the way it is calculated. This bill was approved by the Chamber of Deputies of the Chilean Congress and is currently in the Senate with no set date for discussion. No assurances can be made as to whether the proposed bill will be approved and as to whether, if approved, it will have a material impact on our financial condition.
These and any additional legislative or regulatory actions in Chile, Spain, the European Union, the United States or other countries, and any required changes to our business operations resulting from such legislation and regulations, could result in reduced capital availability, significant loss of revenue, limit our ability to continue organic growth (including increased lending), pursue business opportunities in which we might otherwise consider engaging and provide certain products and services, affect the value of assets that we hold, require us to increase our prices and therefore reduce demand for our products, impose additional costs on us or otherwise adversely affect our businesses. Accordingly, we cannot provide assurance that any such new legislation or regulations would not have an adverse effect on our business, results of operations or financial condition in the future.
