Law firms generally do not go to work on weekends, but it is not excluded that some lawyers work overtime on weekends. The working system of law firms is synchronized with the courts and procuratorates, which facilitates the work.
For law firms, working hours must be determined according to national statutory holidays, but for individual lawyers, working hours are generally flexible. A lawyer's job is flexible. In fact, there are very few people working in the office, and there is no need to rest on Sundays. Some people are not in the office at ordinary times, such as appearing in court, taking evidence and investigating.
