Tomorrow we close acha at 6 which means packing has to work one hour less since they normally finish at 7
Therefore to ensure that we treat everyone fairly all computer employees need to come at 9 because this way their official worktime is at 7 also which means they also get the benefit of working one hour less
*If computer employees would come at 10 and leave at six they would be working 2 hours less than their official working time which would be unfair to packing and people who work 6 days a week
