Changed name for this.
Myself and 4 other colleagues were signed up for an extra qualification course from work, 1.5 years to complete and 10 exams.
We chose to be signed up.
I passed all the exams first time and received my certification + got promoted.
2 colleagues gave up and both left for other jobs.
2 other colleagues failed a number of exams and will have to re-sit them if they wish to get the certification.
I’m now senior to them and although we don’t work directly with each other, when it is the case, I will lead and they will take my insteuctions.
Today during an informal team meeting, one of the colleagues were there and as they were talking about re-sitting exams, they asked me ‘what was my trick to pass all of them first time’
I replied that ‘my trick was to study as much as I could’
The colleague then jokingly said that ‘the assessor clearly liked me, was I studying on his bed?’
Then she laughed - everyone else were silent.
I was so shocked the only thing I could say was ‘not sure how to respond to this question, maybe I need to contact HR for advice’
Then I excused myself from the meeting as I was due to go to another one.
This was at the end of the day so I heard nothing else about it.
No managers were present but other colleagues were there.
What do I do now?
