Getting into teaching is difficult, it requires a lot of qualifications, perhaps more than many other industries, and a lot of dedication. Because of this, there can be a number of frustrating individuals seeking alternatives.
Occasionally patience and luck do not work for some individuals and a career switch can be a good idea. Another alternative instead of teaching can be a support worker or a social worker. These can see individuals take an extremely personal approach to helping children and adults (whatever age they wish) and there may be more luck in terms of job opportunities in these roles.
It can take a lucky break to get into teaching, and some individuals may grow tired of waiting, or perhaps they find that their passion lies elsewhere, if this is similar to your situation, then consider social work or support work, it may just be the job you’ve hoped for.
