The disobedience campaign, which began with doctors, has also spread to some government offices and on Friday won the formal backing of Suu Kyi's NLD party.
Army chief Min Aung Hlaing took power citing alleged irregularities in a November election that the party won in a landslide. The electoral commission has said the vote was fair.
The National League for Democracy (NLD) party of ousted Myanmar leader Suu Kyi on Friday (February 5) threw its support behind a civil disobedience campaign and said it would help people who are arrested or sacked for opposing this week's coup.
In a statement on an official NLD Facebook page, the party denounced the coup and Suu Kyi's detention as "unacceptable" and said it had a duty to provide help to those penalised for opposing the military takeover.
