Limited earning potential
When you work as full timer for a company, you just can earn or get salaries as much as company offer. It will be hard to get higher salaries unless you prove yourself and get higher position in company or you work overtime to increase your earning. Other than that, you also depend no your employer for the salaries and if your employer or company bankrupt, you may not able to get your salaries or may just recovered some of it.
Static professional opportunities
Temporary worker or part timer usually work on limited-time contractual basis which providing them opportunities to meet more people and learn more skill. For full time employee, they have been assigned with specific task when they start their work and they just can focus on the work that assigned by their employer. They will have less chances compared with part timer to speak out their idea and expand their network where they have specific task to be done at their workspace.
Lack of flexibilities
Full time employee may have less flexibilities on their working hour and their working location. Full time employee has to be in the office for business hour while part timer can choose to get their work at home without punching card and just need to get the job done for specific period of time. There nothing can be done where full time employment has contract with company and they need to follow the rules and regulation that specify in the contract.
Lack of opportunity to evolve
Most of the full time employee want to get acknowledgement from company and offer them higher position for greater salaries. However, it is not easy where full time employee just conducts same task every day and not much opportunities for them to prove themselves. If they want to become expert in the field or get higher position, they need to challenge themselves or improve themselves in order to keep themselves updated to the constantly changing market.
