I work rotating shifts with a total of 19 different layers in 27 weeks. Most planners to early, late, night and free. Clearly not enough.
Here you write once its complete layer run on (no matter how is the film, one is completely free and has no fixed targets) appoint the date on which the layer cycle starts and that was about it. You can see how they work on the last day before they retire. No problem.
And if you work it out another layer, it can be without making a change to the mask for this change one day.
The only thing he can not show the hours at the end of the month or enter overtime. But for me it's not important. Therefore full 5stars.
