Who would have thought that in 2025, Biglaw firms would be forced onto the front lines in a battle for the rule of law against the president? Faced with retaliatory executive orders, four firms chose to challenge the unconstitutional orders in court, and each one that did was granted summary judgment. One of those firms is Jenner & Block, and after a year of protracted litigation, it’s now calling attorneys into the office on a more regular basis.

Last week, the firm — which brought in $682,158,000 gross revenue in 2024, putting it at No. 83 on the most recent Am Law 100 — notified associates in its U.S. and London offices that beginning on March 1, 2026, they’d be expected to work from the office four days each week, on Monday through Thursday. The firm currently requires three days in the office and is now one of only three firms ranked in the Second 50 in the Am Law 100 to mandate more time spent on site. What inspired this change? The American Lawyer has additional details:

“The firm’s hiring has helped lead to additional investments in space, which the memo cites in making the change. ‘If we are going to invest in space, we need to use it fully. Major firms across the legal industry are increasingly moving to 4 and 5 days in-office attendance. And so, as we invest in new office space, stay in-line with our peers, and, most importantly, prioritize the interest of maintaining the Jenner culture that sets us apart and carries us forward on behalf of our clients and each other, we believe in-office collaboration is essential to excellence in our work and service,’” the memo stated.

Quite a few Biglaw firms are now requiring four days in the office firmwide, including the likes of A&O Shearman, Cooley, Covington, Davis Polk, Dechert (junior associates), DLA Piper (corporate associates), Goodwin, Hogan Lovells, Latham, Paul Weiss, Reed Smith, Ropes & Gray, Sidley, Simpson Thacher, Skadden, Vinson & Elkins, Weil Gotshal, WilmerHale, and White & Case. Sullivan & Cromwell has taken its attendance policy one step further, requiring attorneys to work from the office five days each week.

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. We always keep our sources on stories anonymous. There’s no need to send a memo (if one exists) using your firm email account; your personal email account is fine. If a memo has been circulated, please be sure to include it as proof; we like to post complete memos as a service to our readers. You can take a photo of the memo and attach as a picture if you are worried about metadata in a PDF or Word file. Thanks.
