Impact of Technology on Careers Employment/unemployment Technology has great impacts on jobs and opportunities in organizations on a whole.
Through the employment of machines, the need for an intensive labour force is reduced. This will result in reduced labor cost and may subsequently result in reduced production cost. Pre-Mix Jamaica has made much use of technology for its everyday operations which has made them less reliant on human labor for certain every day routine tasks. Processing Technology has impacted careers involved with processing in both positive and negative ways. Careers such as quality controlling, batching and maintenance engineering all involved some form of processing.
Positives- • Tasks are able to be carried out more efficiently and in a logical manner, for instance, one mixing truck can mix much more concrete than several laborers mixing manually. Negatives- • The application of technology to processing can result in loss of jobs for unskilled workers • It can also make us overly dependent on machines such that we loose our craftsmanship. • Technology is antisocial and thus can promote this at the workplace. Environmental Careers relating to the environment are very important and they also are greatly impacted by technology.
Pre-Mix Jamaica is located in a built up area where there are institutions such as schools and other business close by. Hence Pre-Mix has the responsibility to be as environmentally friendly as possible, especially because their production of concrete produces a lot of pollutants. In mitigating against this problem, the supervisors at the complex ensure that the compound is watered regularly using water trucks.

The company is a ready mix organization, meaning they manufacture in a batching plant according to a set recipe, then deliver to construction sites.
Recommendations ? It is recommended that enough protective gears are available to visitors on the site for future use. ? It is also recommended that the organization is given advanced notice for research visitors so that they can be well prepared. Limitations ? The length of time of the visit was too short; hence it limited the amount of knowledge that could be gained. ? Not all departments were visited at the company; therefore a lot of useful information was unfortunately not received. Appendices Fig1. 3 Figure 1. depicts concrete being batched into a mixing truck from one of the silos. The Aggregates will then be mixed into the truck so that the concrete may be suitable for use. Fig1. 4 Figure 1. 4 shows samples of concrete placed into moulds. After they are hardened, they are demoulded then placed into a curing tank for seven days. Their strength is then tested by compressing them with machines. Fig1. 5 In Figure 1. 5, there is a heavy duty machine seen on the plant. It is used to get large quantity of materials such as gravel from one point to another. [pic]
