Are you taking Shift manager , People manager , assistant manager or business . manager ? If you are taking shift manager then I ' d say do it . The selection process depends on your store , the course itself is easy when you take your test in London , and you will gain knowledge and experience that will come in handy for all types of job . I can ' t really comment on the other types of management , but I ' d say any education and progression is a bonus and shouldn ' t ever really be refused . One of my colleagues actually won best in class when he took the shift . manager course in London . But he hated the role so much he demoted himself back to crew member within about a month , so if you decide it ' s not for you , It ' s not the end of the world .
