When asked why you want to leave current employers?
Can I answer as follows?
Good firm to work for however due to ages of directors - youngest is 62 this year - there appears to be no forward planning, no introduction of young blood to take over. Directors are first to admit they have done nothing.
Being able to work locally is very important to me and I have been considering a move for a year or so.
Note - we live in a farming market town. Employment opportunities are few and far between. Does the above sound ok?
