What is the antonym of the word 'Leisure'?

Antonym of the word 'Leisure' is work.

While leisure refers to free time spent in relaxation, enjoyment, or personal activities without obligations, work signifies tasks, duties, or responsibilities that require effort and focus. Work typically involves productivity and commitment, often in exchange for compensation, whereas leisure represents a break from such demands, allowing for rest or recreation. The two concepts highlight contrasting states: one of active engagement and the other of restful disengagement.
