The work hours are usually set by the client but working over 40 hours is usually looked down at.
40 hour weeks, which is rare for consultants. Hours are as flexible as the client is usually.
I work 40 hour weeks at my client as that's the number of hours that they bill me for. I do other things that are related to my being at ThoughtWorks outside of those hours but I do not consider this work.
My work hours can be flexible if I need to go urgently somewhere but in general, I do 9 - 5.30
Very flexible 8 hrs a day give or take
40-45. It is encouraged that we work only 40 hours per week.
