The manager gave the suspension of work notice to the Banarhat police station last midnight and left the garden, the sources said.
Another suspension of work notice was put up at the garden gate.
The police had gone to the garden on January 21 after employees protested half pay announced by the management on account of fall in production, they said.
After police intervention, the manager of the garden had declared that full pay would be paid, the sources said.
The garden had closed a number of times in the past because of sickness and reopened recently.
