Things do not always come out the way you expect them to. This is also true for apprenticeships. Whether you are struggling with personal problems, think the training is not as advertised, or do not feel you like the job.
If you are unhappy with your job, whether in the workplace, the duties, or the corporate culture, you may change jobs and continue your apprenticeship course.
It would be best if you discussed this with your training provider. It will be their duty to evaluate whether or not this is a realistic alternative for you and to approve the new employer’s suitability.
