All legal employers should establish policies closing the pay gap between male and female lawyers working in similar jobs, the American Bar Association’s policy-making body agreed on Monday.

The ABA’s House of Delegates approved by voice vote an equal pay resolution at its convention in San Francisco after wrestling with proposed changes to ensure it would apply to all employers of lawyers, not just law firms.

Former ABA President Hilarie Bass asked men in the room before the vote how long they would continue in a profession if a study showed they made half of what “a colleague in the next office” earned.

Recent researchshowed women law partners faced a 53 percent gap in pay at top U.S. law firms.

Bass has been a vocal advocate for women in the legal profession.

ABA resolutions approved by the delegates form the basis of its policy and lobbying priorities.
