NC as you just never know who is reading MN 
I'm applying for new jobs because I can't stand my boss any longer.
The (potential) new work will be similar to my current role and I'm not looking for more money or promotion. The new roles which I'm applying for will be with similar sized companies/firms.
Should I get an interview I'll be asked why I'm leaving my current company.
What do I say without criticising my current boss/employment, which I don't want to do.
Help please!
