What should be done in case of loss of “B” certificate?
In case of loss of “B” certificate, it would be possible to obtain a duplicate certificate
from the Commissioner of Labour by perfecting new “B” form and enclosing a money
order to the value of Rs.1/- in the name of Commissioner General of Labour and
indicating the paying office as “Colombo”. The member could also obtain a duplicate of
the “B” certificate by personally calling over at the Central filing section, 9th Floor,
Labour secretariat, Colombo 05 and paying Rs.1/- as cost.
