Well, in the UK, it is common practice to have 2 references in my CV. So I put the boss from my last job, a farmer, and the boss of the charity I volunteer for. I guess they can call my ex boss if they want, since my CV says what town the Subway is in and you can Google the number. I don’t know if they will, but it’s not impossible.
I’m not sure I can be that honest about it. The position is actually for another food job, as a catering assistant, and it’s for the Government’s National Health Service. So it seems inevitable something about the Subway job will turn up since it seems the most relevant job on my CV.
