Here's the Gurobi code to solve your optimization problem:

```python
import gurobipy as gp

# Create a new model
model = gp.Model("Work_Optimization")

# Define decision variables
john_hours = model.addVar(vtype=gp.GRB.INTEGER, name="john_hours")
jean_hours = model.addVar(vtype=gp.GRB.INTEGER, name="jean_hours")
bobby_hours = model.addVar(vtype=gp.GRB.CONTINUOUS, name="bobby_hours")
mary_hours = model.addVar(vtype=gp.GRB.CONTINUOUS, name="mary_hours")
bill_hours = model.addVar(vtype=gp.GRB.INTEGER, name="bill_hours")
laura_hours = model.addVar(vtype=gp.GRB.INTEGER, name="laura_hours")

# Set objective function
model.setObjective(7 * john_hours + 5 * jean_hours + 4 * bobby_hours + 2 * mary_hours + 4 * bill_hours + 3 * laura_hours, gp.GRB.MAXIMIZE)

# Resource data
