Coming in late at my work means whoever you are taking off is now leaving work late. Assuming they stay on past their official end time, which they don't have to do. If they are doing a safety critical role that has to be covered at all times then you are looking at finding a 3rd person to cover while the late person comes in. A whole lot of hassle, no?It sounds like one though, binning someone for lateness twice in 3 months is ridiculous. Thankfully I work for a company that is driven by results, at the end of the day that is what matters.
