Prompt:
1 week rota for my employees for 15th-21st December 2025, I have 2 FT (26-34 hour per week) and 4 PT employees (16-24 hours per week). Full-time employees are Maria and Nuria, part-time employees are Nate, Jack, Ben, and Finn. We are a bar closing at late times so the shifts are 16:00-22:00, 16:00-23:00, 18:00-01:00, 19:00-01:00, 1 person per shift for Thursday-Sunday inclusive. Monday-Tuesday shifts are 16:00-21:00, 16:00-23:00, 17:00-23:00. We are closed on Wednesdays. It's coming up to Christmas holiday season so I'm having trouble making this rota around my employees booked days off. Can you make this rota? 

Full-time employees are also senior staff, so I need at least one FTer to work the closing shift to cash-up every night we are open (the PTers aren't trained to do this). Also, Nate and Jack who joined us for this holiday period are both under-18 so they can't handle alcohol alone, don't schedule either of them unless there is at least one adult working at the same time. Maria has a family event on Friday, so don't schedule her any shifts that day, and on Sundays, she needs to finish before midnight because buses don't run late. Ben goes to university so can't do shifts starting at 16:00 on the weekdays, 17:00 and after is okay. 

Don't schedule FT staff to work more than 5 days in total, and PT shouldn't work more than 4 days in total, this is in their contracts. I want to be a good employer, so I want the PTers to have at least 2 consecutive days off (including our closed Wednesday), it would be annoying if they had to come in to work every other day. I need the total hours for each employee for this week to calculate payroll, FT are on £16.5 per hour, Nate and Jack who are only with us for this seasonal rush are on £14 per hour, Ben and Finn who are our regular PTers are on £14.5 per hour, sum up each employee's total hours at the end.

Evaluation criteria:
The response should schedule a maximum of 5 shifts each for Nuria and Maria.
The response should ensure that each of the full time employees are assigned a total of between 26-34 hours per week (based on adding up the scheduled shift hours, not just the total explicitly stated in the response).
The response should state the total hours correctly for each employee. For example, if an employee is assigned 41 hours in the rota, the total hours should state 41 hours.
The response should assign a total of 16-24 hours of shifts in the week for Nate, Jack, Ben, and Finn.
The response should assign at least one closing shift to either Maria or Nuria for every day apart from Wednesday in the rota.
The response should not schedule Nate or Jack to work any of their shifts alone. For example, the prompt should schedule one of the adult employees to work alongside them in every hour of their shift as they are both under the legal drinking age and cannot handle alcohol alone.
The response should not schedule Ben to work a shift starting at 16:00 on a weekday (Monday-Friday inclusive).
The response should assign 2 consecutive days off work (including Wednesday's closure) to Nate, Jack, Ben, and Finn.
The response should not schedule more than 4 days with shifts for Nate, Jack, Ben, or Finn.
The response should create a rota for the 1-week period from Monday, 15th December 2025 to Sunday, 21st December 2025.
