This country was built on freedom of religion and freedom of speech. Whether its right or wrong a person should not be fired or suspended for making a racist remark.
You shouldn’t really have sent it
But they have the right to suspend you, because it was racist
Ive noticed how racism works both ways, yet only one way is punished, If a black/coloured/etc.. made a racist remark to someone who was white, then nothing would really happen, however, if it happened the other way, then it would be taken seriously,
Countries are so worried about being seen as racist that they will bend over backwards for people of other nationalities for fear of gaining a racist label
However, Racist or not, its considered abuse and bullying, in any respectable company, they will not tolerate it, so they had the right to punish you,
Your lucky that you haven’t lost your job all together, i know people who’ve been fired for smaller things than what happened with you
Try not to do it again-otherwise id be expecting to lose my job if i were you, once is a mistake, you were caught, its now in the past, doing it again is just plain idiocy
All the best xxx
