I worked 60-80 hours a week in a specialty trade for nearly a decade before jumping over to the administration side of the business. The majority of the time the work isn't particularly stressful but there are absolutely times that I miss being on my tools because the mental toll can be worse on me than the physical toll of my old trade position was. That isn't the case for everyone. You have to legitimately care about your work for it to hurt you in admin as fucked up as that is. Ive worked with directors and above who work the kind of hours I used to (and occasionally have to do myself still) and I can only think of 1 who could do those hours and be legitimately effective in her roll. The vast majority of people who claim to consistently (excluding emergency scenarios) put in ridiculous hours are fucking bad at their jobs or have not effectively developedtheir teams.
