Well here is a current example of the problems. I hurt my back yesterday morning at the gym. It wasn't too bad and I am sure muscular, but gradually got worse through the day. By about 6pm I could barely move.
Dilemma: most of my work in the morning needs to be texted for access. Do I text knowing there is a good chance I won't be able to work? I did text, now this morning I wake up in serious discomfort.
There is no way that most people would consider going out to do the kind of work we have to do, but now I have an additional pressure to go out or if not I have to text again to say I can't make it which makes me look unreliable. Particularly if for one reason or another I have had to cancel recently due to bad weather for example.
So there are reaons other than being a "neanderthal" that make texting before problematic. I text for access only now, but unfortunately that does account for most of my work. I used to get quite a few cancellations, but I get very, very few now as I have culled the round of them.
