0 a short period when someone stops work to smoke a cigarette: --
The government planned to ban smoko for its employees.
Some of them disappeared for their smoko.
A local engineering company installed an old steam whistle operated by compressed air; which has become the town smoko signal, sounding at 10am, noon, and 3pm.
Smoko breaks of a half hour each are at 9:30 am and again at 3 pm.
Today the mine's smoko room sits near this site.
