This happened to me...back in the 1970's, I was a makeup artist and became a field rep for Redken Labs....I loved the job!! the travel, etc...after 3 years, they offered me the position of supervisor...I did not want the job as I saw what my supervisors went thru!! all the paperwork, etc..and I am not a 'mangerial' type of guy!! So I asked them if I could try it for 6 months or even one year, and then if I found it not satisfactory, go back to being a field rep?? they said, "No; if you get a promotion, you continue going 'upward and onward' with the company"......so, with a very heavy heart, I quit.......I do not regret my decision, but just wish the company would have let me try it...oh well!!!
