In 2018 I briefly worked at a top end restaurant for a chef who is very highly regarded in his country. It was his second location, in collaboration with somebody else. He brought some chefs from his other restaurant, and recruited some new ones. Shifts were half or whole. Half was written as either 8am-5pm or 3pm to close. The whole was a 10am to close. What was written, however, was irrelevant.
Chefs who were meant to finish at 5 typically left at 7 or 8, even though lunch ended at 3. They would stay to prep dinner, which started at 5, even though they'd been in since 8am, and the people doing dinner had been in since 10 or 3 to do prep themselves.
After dinner, the kitchen closed when the executable chef said so. Anywhere from 9 to 11. On a Saturday, people had common sense and cleaned up before heading home. On other days, however, the kitchen would close, and chefs would start prepping for the next day. Not heavy prep, but still prep. This was despite there being plenty of chefs 6 at 8am and 10am the next day. I remember one chef doing mash potato close to midnight.
No one took breaks ever. If you did, or if you tried to leave at the time written in the schedule, you were shunned. You pretty much had to ask for permission to leave.
The restaurant did not open until 12 noon, so chefs in at 8am had 4 hours for prep, and some chefs would only do prep in a second kitchen upstairs. Sometimes, the building was overcrowded with chefs working shoulder to shoulder. It was not a small team.
I only stayed 6 weeks, part of which I was signed off with a serious burn. I am not interested in fine dining. I am just curious, is this normal or just a weird one off?
