What time of the day did work for professional & clerical jobs begin & end 100, 200 & 300 years ago?

It isn’t real.

See here Is the 'Rules for Teachers - 1872' List Real? | Snopes.com

Well, his was for a general store, not for teachers.

Ahem, so it does refer to a list for general stores farther down the page. Sorry!

:o

A lot of these lists are hoaxes.

I don’t get it. A Spaniard found Glasgow too hot at 4 in the morning? Hens like hot places?

Too bright. Hens get up early, like roosters do.

London is surprisingly green for a city of its size, and logging was allowed in places like Richmond (Great) Park right up to the turn of the century. In any event, I suspect Bob Cratchit would have mostly burned coal in his fireplace.

They used coal.

Or peat.

Or crutches!

Samuel Pepys’s staff in the Navy Office were doing clerical work in the 17th c. I don’t have time to go through the diary but there are plenty of references to the working routine. Pepys eventually gave up writing the diary in the belief that he was going blind. Candle light made his eyes ache increasingly as he got older and the optical aids of the period could not cure his problems (which probably involved astigmatism).

What he said.
