I used to have to lie all the time at work, when I ran the dispatching of the field technicians.
We were seriously overbooked, but never wanted to turn down work...
So I had to lie and invent excuses why our guys never showed up on the appointed day.
It was brutal and I hated it.
The new schedule guru is very good. She's upfront with the customers about the workload and books a realistic starting date for each project.
