March 4 (Reuters) - Lawyers at more top U.S. law firms

are being told to show up to the office four days a week, as

corporate clients also step up demands for office attendance.

Wilmer Cutler Pickering Hale and Dorr and Paul, Weiss,

Rifkind, Wharton & Garrison are each expecting lawyers to be in

the office four days a week starting this spring, up from three,

spokespeople from the two firms confirmed.

Other large law firms including Davis Polk & Wardwell;

Skadden, Arps, Slate, Meagher & Flom; Ropes & Gray; Weil,

Gotshal & Manges and Vinson & Elkins have adopted similar

four-day-a-week policies since 2023.

"By being physically present together, we better develop our

talent and ensure that we continue to deliver the level of

extraordinary service that our clients expect," a Paul Weiss

spokesperson said in a statement.

Friday will be a "remote-option" day under the new policy,

which takes effect for all Paul Weiss lawyers and business

professionals on April 30.

The new requirement at WilmerHale takes effect on April 28,

according to a person familiar with the policy change.

More than half of respondents to a survey last year said

their law firm requires lawyers to come in at least three days

per week, according to an April report by the Thomson Reuters

Institute, which shares the same parent company as Reuters. The

data included 350 responses from 105 U.S. law firms.

U.S. bank JPMorgan Chase ( JPM ) in January asked its employees who

are on hybrid work schedules to return to the office five days a

week starting in March, an internal memo seen by Reuters showed.

Amazon.com ( AMZN ) said in September it would require employees to

return to working at company offices five days per week.

Not all law firms have imposed stricter in-office

requirements since the pandemic. Quinn Emanuel Urquhart &

Sullivan and Husch Blackwell still allow full-time alternatives

to in-person work. Phoenix-founded Fennemore Craig last summer

also launched a new program to hire lawyers in locations where

it does not have offices.
