I am a man and worked in fastfood during my studies.

I was offered a permanent contract immediatly after my first month, while there were also a lot of women with kids working there who had been on temp contracts for years. Probably because I could work at night; the mothers worked during schooltimes. Any time someone got pregnant, their contract was not renewed.

In this situation I had an advantage because of my gender. This was not because the business itself was specifically sexist, in fact almost all of management were women. Instead, the systems in place made it so that financially smart decisions negatively impacted women.
