Hi Dipti,
The infrastructure industry refers to core sectors of the economy: Cement, Oil & Natural Gas, Power, Steel, Petroleum refined products, etc.
The challenges for the sector can be identified during TWO phases: the Project phase and Operation phase.
In the project phase, the likely issues include acquisition of land, identification and establishing linkages for sources of raw material, water, and major markets; identification of technology, equipment vendor, major construction-erection contractor/agency; identifying a host of various agencies for sundry works, establishing a PERT network, and monitoring progress of work; establishing cordial and collaborative relations between various agencies at the work site, etc.
You can get an idea of the magnitude of the work if you imagine up to 10,000 persons working on an infrastructure site, in a precise manner, in a pre-planned way. Here, timely delivery of resources is critical to the completion of tasks, which form input for the next task.
In such a site, skilled manpower is always a scarce resource. As such, skilled persons are always sought after by resourceful organizations/contractors/sub-contractors to complete assignments on time, to avoid heavy penalties as a consequence of delays.
So, in this background, an agency can leverage "HEALTHY RELATIONS WITH EX-EMPLOYEES" by requisitioning their services as a freelancer, at an opportune time, and pay a premium for their time. Since such deployments are for short bouts of time, HR of that establishment needs to trade-off between "High rewards & Sustainability" of such rewards over a period of time.
Hope I have been able to create the scenario...
