A general strike had been called for 12 June, the day of the planned resumption of the second reading of the extradition bill.
The Hong Kong Confederation of Trade Unions (HKCTU) appealed to workers to join the protest; hundreds of businesses closed for the day and numerous workers went on strike.
Affiliate Hong Kong Cabin Crew Federation also called a strike.
HSBC, Standard Chartered and Bank of East Asia closed some central branches; some of the banks and the Big Four accounting firms had agreed to flexible work arrangements for staff; Hong Kong Jockey Club shut down three of its central betting branches, citing employee safety.
The Hong Kong Professional Teachers' Union (HKPTU) called on its members to attend a protest rally after school hours on that day.
Student unions of most of the major higher education institutions had also called for student strike on 12 June; 50 social welfare and religious groups also took part in the strike.
The Catholic Diocese of Hong Kong urged the Hong Kong government and the public to show restraint, and the administration "not to rush to amend the extradition bill before fully responding to the concerns of the legal sector and the public."

Another call to "picnic" at Tamar Park on 12 June attracted close to 10,000 responses.
The Legislative Council Commission issued an amber security alert.
The protest zone outside the building was closed and access to the complex was limited.
Sit-ins began in the morning and a large crowd built up at the MTR exit.
In the early morning hours, the crowd rushed onto Harcourt Road and Lung Wo Road, blocking these streets in scenes reminiscent of the 2014 Umbrella Movement protests.
A banner with "Majority calls on Carrie Lam to step down" and "Withdraw the extradition bill, defend One Country Two Systems" written on it was hung from the Admiralty Centre footbridge.
Around 11 am, the Legislative Council Secretariat announced that the second reading debate on the extradition bill had been postponed indefinitely.
