Sorry if this has already been asked before.
If there are numerous examples over a period of time of somebody not following procedures but in a fairly minor way, can they all be added together and dealt with at once for disciplinary purposes? Or should each specific example be dealt with at that time, even if it meant invoking disciplanry processes for fairly minor infractions?
Together each incidence adds up to a picture of someone who is clearly incomptetent but on their own they are fairly insignificant.
I'm trying not to out myself by giving examples but say for instance somebody worked in a shop and one week they left packaging in an aisle, the next week they gave someone too little change, the following week they stocked a shelf incorrectly - none of them would be massive misdemeanours individually would they, but would a manager be justified in bringing someone in three, four weeks after the first incident and listing them all together?
TIA.
