Employees benefit from calls out of hours. How? The employer is able to offer better service to customers, and make more money, and the employee can negotiate a higher salary from the more profitable business. Employees who are inflexible cannot offer the same level of service to their employer and its customers; they'll on-average be paid less and measures like this increase production costs, making goods and services slightly more expensive.
This law reduces the extent to which flexible employees can add (and extract, via hight salary!) value, and the extent to which customers receive timely service.
