If you get a job doing something with English, you'll probably spend a lot of time job hunting, honestly. Or you might have a job going on for the next few hours, days, weeks, months or years, editing a textbook, or writing copy for a website or advertisements, or proofreading business documents or curriculum or test material, or giving suggestions to writers for editing their fiction books, or writing your own book or trying to get it published. Or you might be a teacher and be spending up to 8 or 9 school periods a day with classes full of students (and carefully watching how much water you drink because it will be a while before you can get to the bathroom!). Or you could be a librarian, meeting the public, reshelving books and media, buying books for the system, helping find books in other library districts, helping keep books in good repair, running a story hour or a computer class for community members, etc. You might be someone who decides to help people build websites, or become an audiobook narrator, or a book critic.
Basically, your work week will involve doing whatever you have to do to make sure you're making enough money per week to pay your bills!
I can't speak to the psychology side of what a workweek looks like but I earned my degree in English and work in a writing-heavy field (technical writing) and my work week is 40 hours. There isn't going to be a one-size image of what a work week looks like, it will really depend on what field you are in and what specific job you do. A day of work could consist of many emails, meetings, training, so many factors could come into play.
