**Image 2**

Image 2 is describing how overtime is calculated when 8 hours work shift is published, i.e. 9:00 - 17:00 work shift.

- first graph represents calculation for working hours 9:00 - 19:00 ( 17:00 - 19:00 - 50%)

- second graph represents calculation for working hours 8:00 - 17:00 ( 8:00 - 9:00 - 50%)

- third graph represents calculation for working hours 8:00 - 13:00 (no overtime)

- forth graph represents calculation for working hours 8:00 - 19:00 (8:00 - 9:00 - 50% and 17:00-18:00 - 50 %) ( 18:00 - 19:00 - 100 %)

**Image 3**

Image 3 is describing how overtime is calculated when expected working times are set to 06:00 - 20:00.

- graph two represents work shift 05:00 - 11:00 ( 6 hours work shift and 1 hour overtime because of expected working time starts at 06:00)

**Image 4 **

Image 4 is representing expected working times set to 05:30 - 22:00. Work shift is done 04:00 - 14:30 and calculation order is as follows:

1. 5:30 - 6:00 - 30 min 50% overtime

2. 14:00 - 14:30 - 30 min 50% overtime

3. 04:00 - 05:00 - 60 min 50% overtime
