If you are happy in the job you do and with the company you work for then you may wish to start progressing up the ladder to obtain a promotion. Within some companies this is a fairly easy process but with others, it may take a number of years and a lot of hard work to allow you to take on more responsibility.
If the business is family run, you may find that the management positions are mostly held by family members and therefore you have little chance of progressing, but this is not always the case. If you can show loyalty to a company and work hard this may be enough to see a promotion on the cards.
Larger organisations sometimes have set time scales where your progress will be reviewed and a promotion may be offered. This is a more structured way of doing it but can take longer.
