According to the International Monetary Fund's (IMF) Global Financial Stability Report, the current global financial status is a balancing act of sorts.

This means it’s in the best interest of businesses to generate as much business / revenue as they can, thus creating the ability to employ individuals. Further, it is important to realise that many people cannot afford to quit their jobs. This often means if there’s a large exit of staff, they’re often leaving for reasons out of their control – in other words, retrenchment and retirement.

On the other end of the scale are the graduates who’re freshly out of the academic and training factory that is a college or university; thirsty for experience and ready to pay off that student loan. Graduate recruitment and graduate programmes show an interesting conditioning, so to speak, that is occurring in the life of the young grad. They’re faced with challenges of finding employment and holding down that job. This often gives them very little time to focus on their careers and, before they know it, they’re the proverbial worker bees!
 
Quite simply, a worker bee is a person hired to get the job done, and do get that job done on time.
 
Oh, for the record, there’s nothing wrong with being a worker bee. If companies need to get the job done and people are willing to do the hard yards, then so be it.
 
Similarly, if workers are happy to do the job to the best of their abilities, then again, “everything is awesome” – LEGO Movie!
 
The key is to get the right person to do the job...
 
Finally, it can also be assumed that with the amount of graduate programmes in existence it means that companies are actually generating enough business to sustain this in-take. This somehow creates a "balanced" ongoing employment equation with the number of workers who leave a company.
