Most lawyers work on average of 60 to 70 hours per week depending on how much work they have to do and how many clients they're working for.
Lawyers will also often have office workers who take calls from clients etc and then pass their info onto the lawyers.
If the lawyer is backlogged or really busy the lawyer may even work on weekends and although lawyers are pretty high paid they really don't earn enough money for the amount of work they do.
And for the work they do keeping you in good terms with the law.
