> 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. The business can put that into their contract so that a prospective employee can make a conscious decision: For example, I have two offers, one for x% higher salary but the contract stipulates a requirement for me to be available after-hours between Xpm-Ypm on x days of the week, I can then make the decision whether the x% more money is worth the stress and the free time I have to give up. That's how our business introduced on-call: it's opt-in and there is specific remuneration for being on call and for responding to an issue.
