In the Labour-Discipline Model (LDM), the employer sets the wage to minimise the cost of effort. Using the LDM, illustrate and explain how a change in conditions affect the employee's best response function (BRF) in the following hypothetical cases:

1. The fintech firm you work for introduces a well-planned four-day workweek model. The other firms within the sector have a traditional five-day work schedule.
2. You face two different work-life trajectories in South Africa, one as an unskilled worker, the other as a highly-skilled worker. Use separate BRF diagrams to compare the two different outcomes.
