When it comes to the work-life balance of a management consultant, Saturdays are usually a day off, while Sundays are often spent catching up on emails and other tasks. Working on the weekends is not an expectation at McKinsey, and is extremely uncommon. However, as a consultant, your main goal is to make your customers happy, so there may be times when you need to work on the weekend. In addition, there is rarely any downtime in consulting, so you may not have time for coffee breaks or errands.
When deciding whether to pursue a career in consulting, it's important to consider the geographical dispersion of clients in an industry in relation to the location of your office. This will help you balance work and personal life. If you need approval to work on the weekend, it's best to go to Human Resources and talk to them. They will likely refer the matter to the managing partner of the office, who must give their approval.
