How to write a variable break?

For example, in a manufacturing unit 50 employees are working, all the 50 employees will not take a break at a time, so 25 people will take a break around 11:00 to 11:30 and another 25 people will take a break around 11:30 to 12:00.

Variable or flexi break means if you are fixing the break as 10:00-12:00 and saying that only 30 min break then they can take a break of 30 min at any time in between 10:00-12:00.

In config, under time management and then work schedules, go to break schedules, and create two break schedules (1) 11-1130 and the other for 1130-1200. I think each will have its own DWS. In this case for break schedule 1, the DWS will be 8000 and for break two it will be 8001. Create work schedules for each and assign to the relevant group of employees. This is the solution I could think of.
