Regarding breaks.
Technically, One Piece has not rested since chapter 984, that is, there have been 4 issues in a row of the magazine with One Piece chapters. The breaks in recent weeks have been breaks from the Jump for vacations (last week) and adjustments due to COVID-19 (the 4th week of July) and therefore those weeks have "rested" all series . Yes, possibly Oda has really rested these days but hell, these are vacation days that everyone who works deserves.
The One Piece work situation is VERY complicated due to COVID-19. So much so that even Volume 97 of the series, the new Color Walk 9 artbook or One Piece Magazine Vol. 10, have had to be delayed for 2 weeks due to problems related to the virus.
Oda is working right now with minimal contact with assistants or editors (confirmed by Shueisha and himself). So, if already in a week with everyone working at full capacity, deliveries are arrived in just in time, imagine having been working for several months with less help.
Aranın nedeni oda nerdeyse asistansız calışıyomuş coğu işi tek başina yaptıği icin yetiştirmek de zorlanıyormuş serie'yi.
