Implement a flexible public holiday policy that embraces multiple nationalities and religions
Big multinational companies can have employees from all over the World. Obviously, their employees have different nationalities, religion and beliefs. Some employees may feel that their religion or beliefs do not match with the public holiday schedule of the country they are working in.
To solve this issue for their employees, Spotify implements what they call "Flexible Public Holidays". According to Spotify, this is how the process works: "Work on a holiday, report it in the HR system as a worked Flexible Public Holiday day. Then take your day off and report it as a Flexible Public Holiday day off." The end result is that the amount of time worked by the employee doesn't vary, so it doesn't have any cost for the company.
Let employees make a day-off trade
Employees have the choice to work on a day that is listed as a public holiday in the country they work in, and in exchange they can choose another day that a priori should be a working day and make it a holiday for them. The goal of this is to let the employees have the freedom to take a day off work in the day or days that they really want to celebrate due to their religion, beliefs and ideals.
Consult with managers for approval
It is important to point out that managers do not judge or ask employees why they are celebrating any given day. However, they need to be informed in order to plan in advance and to ensure that the employees' team doesn't get hurt by him or her taking that particular day off.
