Two types of computer consultants can be hired: full-time and part-time. The full time consultants work for eight hours in any of the following shifts: morning (8 AM- 4 PM) afternoon (Noon – 8 PM) and evening (4 PM – Midnight). Full-time consultants are paid $15 per hour.

Part-time consultants are paid $11 per hour.
An additional requirement is that for each part-time consultant on duty during any time period, there must be at least two full-time consultants on duty
