So if the boss is telling you how to write and lay out a letter, do you get to tell him/her how to do his job?
I thought not. Stand up for yourself.
I had the same situation years ago after a management buyout when the new MD came in one day and told me he didn't like the way the letters were laid out (I had immediately changed to something more modern when the 'old guard' had gone!
So I argued the case that I wasn't about to tell him how to put together an advertising campaign (we were an ad agency!) for our clients as I had no advertising qualifications - what were his secretarial qualifications and could he even operate a keyboard (this is also pre-computers!)
He soon shut up.
{For those of you who don't know me, I can, however, be quite formidable when standing my ground; if you're not so confident, take a variety of mail you get personally (or in the office, whichever) that you like the way the letters are addressed, and use these are your argument (obviously you're going to exclude the ones done the way bossie does it!!!)
Good luck, let us know how you get on!
