If I was you I would mark no and then explain to them why you answered it this way. Most employers will understand why you don't want your current employer to find out you are looking for employment elswhere. A different perspective As someone who evaluates applications and interviews and hires people I would unequivocally state that you should always answer yes.
Ing no to this question indicates you have something to hide. Any company looking at applicants already assumes the candidate does not want their current employer to know they are searching for a new job, and of course it will show on your application that you are currently employed by said company. If somebody does contact your current employer, it means you already have the job and they're following up by checking facts.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
