I think most wouldn't use your plan Richard not because it isn't a great idea but rather that they don't trust themselves to be able to hold up their end of the bargain I.e turn up when they say they will. I would be too scared that for whatever reason I wouldn't be able to stick to it religiously and the whole thing would go belly up. I imagine if one day is missed it has a domino effect on the entire thing.
yes i think you are right.
it does definitely add pressure to us to get all the cleans done on time, which is good, and sometimes not so good..
it doesn't help when i am building a new round up as we get a bottleneck before we take on a new window cleaner and every one is working at maximum. with a more flexible system you can.. well flex the rounds a little
but like i say, it does keep our monthly income very steady, and maximises our earnings off regular cleans
if i were a one man band i wouldn't do it this way. i would want more flexibility
