Here's the Gurobi code to solve the optimization problem. The code defines the variables, objective function, and constraints based on the provided input. It then solves the model and prints the optimized solution if feasible, or indicates if the problem is infeasible.

```python
import gurobipy as gp

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

    # Create variables
    variables = {
        'hours worked by Jean': model.addVar(vtype=gp.GRB.CONTINUOUS, name="x0"),
        'hours worked by Peggy': model.addVar(vtype=gp.GRB.CONTINUOUS, name="x1"),
        'hours worked by Bill': model.addVar(vtype=gp.GRB.CONTINUOUS, name="x2"),
        'hours worked by John': model.addVar(vtype=gp.GRB.CONTINUOUS, name="x3"),
        'hours worked by Dale': model.addVar(vtype=gp.GRB.CONTINUOUS, name="x4"),
        'hours worked by Laura': model.addVar(vtype=gp.GRB.CONTINUOUS, name="x5"),
        'hours worked by Mary': model.addVar(vtype=gp.GRB.CONTINUOUS, name="x6"),
