who's right?

i have two jobs. one is in a costume hire store, one is in a cafe. i have been working (officially) in the costume store for about 6 weeks, but unofficially for 6 months. the boss knows i have been doing some work, but is unaware of exactly how much (he thinks maybe a day every week or two, truth is closer to a day or two every week). for the next three mondays i am going to be working with the CH store manager, shadowing, then being shadowed to make sure i know what i am doing. i have been working independently and successfully for ages, and in my "training" period with him i have proved that i can do everything he has asked of me, with skill and accuracy. I have proved myself as a competent worker, and yet he continues to treat me as a trainee who must be supervised.

I have been working at the cafe for less than 2 weeks. a grand total of 6 shifts now. last week i was offered the chance to do my certificate 3 in hospitality through them - they pay for me to do the course. this was after 3 shifts. i accepted and today we sat and talked about what it would mean. permanent part time, which means guaranteed hours, holiday pay, sick leave... a qualification i can take with me if/when i decide to move on. a near future promotion to shift supervisor with a view to part time manager by the end of the year.

so. who is right? am i an incompetent noob who has to be watched, or am i a fast learning hard worker worth keeping and training for bigger and better things??? i know which one i am...

that is all.
