If you are looking for a job with plenty of vacancies and where you will be very much in demand, then consider training as a chef.
OK, the downside might be some unsocial hours and probably split shifts, but, if you want a job where you will never need to worry about being unemployed, then cooking in a restaurant or pub kitchen may be the answer. Nowadays, every high street in the country has a good choice of cafes, fast food restaurants and pubs and bars. Thirty years ago, when you spent the evening in the pub, you would be lucky if there was more then a packet of peanuts or pork scratchings on offer if you felt peckish. Now, just about every pub offers a good choice of food, at lunchtimes and in the evenings. As a result, there is a real shortage of chefs and kitchen staff. So, if you have an interest in cooking and are not afraid of hard work and don’t mind working evenings and at weekends, then you could be guaranteed work for a very long time.
