Top Biglaw Firm Opts For Three-Day Office Mandate In A Four-Day World While peer firms ramp up to four mandatory office days, this firm says three is enough. By Staci Zaretsky on November 05, 2025 1:31 pm Share Copy LinkCopy Link As law firms race to tighten their in-office policies, most are now pushing for four days a week — though a handful are taking a more “modest” approach, asking attorneys to come to the office just three days a week. How refreshing. Arnold & Porter — a firm that brought in $1,193,720,000 gross revenue in 2024, putting it at No. 51 on the Am Law 100 — recently announced that come 2026, it would be making “very modest adjustments” to its in-office policy, specifying that all attorneys and professional staff would be expected in the office three days each week, on Tuesdays, Wednesdays, and Thursdays, during normal business hours. Leading up to this new attendance mandate, A&P will be in “virtual operating status” firmwide during the week of Thanksgiving (November 24-28) as well as the final two weeks of the year (December 22, 2025 – January 2, 2026). As part of a memo sent out this week and viewed by Above the Law, Sean T. Howell, the firm’s CEO, said, “We look forward to spending more time together in the year ahead and to continuing to build on the success and sense of community that make our firm so special.” As soon as you find out about office attendance plans at your firm, please email us (subject line: “[Firm Name] Office Reopening”) or text us at (646) 820-8477 .
