The discovery is a remarkable achievement for the academics and experts who go on busmen’s holidays to work at the site near the Step Pyramid of Djoser, the oldest such structure, built 1,000 years before the Valley of the Kings.

Can anyone please tell me what a busman's holiday is?
Here's a personal impression of a busman's holiday:
A busman carries people around in a bus for a living. When he has a holiday, he finds himself back on the bus to travel to wherever he wants to go.
A busman's holiday, so restricted, still involves what he does to earn a living.
Broadly applied, when one goes on a busman's holiday, no matter the profession, it simply means that much of what you are doing for pleasure is tied up in those same activities you encounter in making a living.
The term busman's holiday may be used either positively or negatively.
Kinda like the postman going for a long walk to relax?
Yeah. My wife runs a preschool. When we visit our daughter and my wife spends some days entertaining our grandson (that's expected, she being an expert and all), that's a busman's holiday for her.
