As for the commentary, a deep sigh would be enough. But apparently, it is now forbidden to make things more efficient yourself. God help us all!
Although it not applicable to this case I've seen enough episodes of Air Crash Investigations or Seconds From Disaster to have seen the implications of people deciding to make something more efficient by yourself.
It's always worth asking why before changing things to make them more efficient. Sometimes the rules are there for a reason.
One of the many merits of those episodes lie in the fact that they show both cases where circumventing something that was placed there for a reason causes accidents, and the cases where not circumventing something that was placed there for a reason causes accidents. Given the amount of stuff in the episodes, I can't say which represents the majority. Swissair mid-air fire being one of the examples where doing everything by the book caused the plane to crash since the pilot failed to act in time - but was doing everything by the book. The iconic episode of Hawaiian flight were 10 metres of the airplane roof ripped off in mid-flight could have been prevented had the crew reacted on a passenger's comment on the fatigue cracks on the fuselage.
But as you said, sometimes the rules are there for a reason, and my addendum to that is no matter how good or bad the reason itself is.
Did anyone think of driving down and asking the people he delivered to if they were getting their mail? Would have thought that would clear that question up in under a day....
NEIN NEIN NEIN NEIN!!! Das would be going outside ze company guidelines, and it would be bad PR for ze company to go around asking the people whether they noticed their shipments are missing! It's a lot besser to go through die Polizei channel - and let ze person who has actually done service feel guilty for it!
All kidding aside, even with these explanations, what happened is still wrong, and to me, incomprehensible and indefensible from the side of the company leadership. The strange thing is that the superiors here really haven't had any reason to suspect anything (no missing mails) during the
years of service, and lacking post is something that is very quickly noticed and complained about. Common sense says that the new comer is most likely wrong in his assertion, and show him how this can be done faster - assign him to go with the faster guy for a day for example. However, to proceed to court indicates lack of trust towards the employees from the side of the employer. Actually, reversing the situation and doing a claim of groundless denunciation of this case here would actually stand a chance of getting through the court.
Of course, the bigger question is, as somebody pointed out, why hasn't the company replaced the official route by the optimal route a long time ago? This again points out towards the non-reacting leadership, though that problem is quite the same anywhere in the world.
