I think it's normal to work 50-60 hours a week if you don't actively track your time. When I was going to the office, I actually worked a lot less. I averaged around 35-40 hours. Now that we all are remote, I find myself working 45-50 hours a week. It's too easy to accidentally go over since I do not have to worry about leaving the office at a particular time due to commuting. However, in general, I feel much more relaxed then before and I do not mind the extra work. I do not let it get out of control since, every hour I work extra, my salary per hour decreases. I like to keep it as high as I can since it makes me feel that my time is worth it.
