Abstract
Employee or labor scheduling is associated with assigning an appropriate number of workers to the jobs during each day of work. It requires determining when staff members will work and when part-time, full-time workers will be needed to work. It is obvious that the number of employees wanted on duty throughout the week may fluctuate depending on health or family issues of the labor and the employer’s requirement for a particular job; Scheduling forces us to systematically identify and analyze about all the tasks that need to be done on a project, the expected time each task might take, the expected requirement of the workforce for the job in terms of size and quality of employee personnel and the expected labor expenses. As the availabilities of the employees may vary and change from week to week; hence the scheduling becomes more essential for the smooth running of a project or shift. This paper focuses on a constructive method for solving Labor Scheduling problem encountered in a construction company, suggesting an estimated labor cost over a week and the requirement of part-time labors in each shift, using linear programming techniques, thus, providing a logical way to organize these tasks and produce a new schedule each week, by the virtue of the changing demand for service while minimizing labor cost and maximizing labor preferences.

In a construction company when we are estimating for a particular the job we look for some vital information on the steps of production, an indication of what materials we need, when we need, the current cost of the materials, Whether the labor drivers are time variant or time-invariant, Determine the time interval for tracking the time variant labor drivers, an indication of how long the job will take, and any an unwanted situation which may affect the completion of the job
Reconstruction of the schedule with available staff is usually simple, changing the schedule may lead to adjustments to other Job schedules as well. This is the daily report of the requirement of different categories of manpower for a particular job to be done on a particular shift in a day in a construction company (1, 0) represents the availability of that particular manpower for a particular shift. 1 for a particular cell represents that the particular category of employee is required for a scheduled job and 0 represents non-requirement of the particular category of employee [31]
Summary
Employee scheduling problems are commonly faced in the service industry [1] [2] which include the scheduling of nurses in hospitals [3] [4] [5] [6], scheduling. The scheduling process helps the contractor to formulate an overview of how the project is going to be laid. Detailed planning of schedule is prepared before execution starts in an area In their simplest form, the Scheduling which is a classic operation research problem provides the contractor with structured planning process while they are reviewing the plans and figuring out the sequence for building the project or the assignment of days-off, as in some of the less complex settings for the scheduling of nurses. In a service organization or in a Construction company the front-line managers or contractors have to perform the important task of cost-effective labour scheduling. At any given time, having an inadequate number of employees or employees lacking the necessary job-skills—can result in substandard customer service; exasperated, overworked employees; and delay in completion of the project and lost sales. Labour or workforce scheduling is the process of balancing customer demand with employee work requests without compromising much on profitability
