Do you think immigrants are treated bad?

In my opinion I think that the way they're treated bad and good. Some
immigrants are treated fair while others are treated bad. An example of
immigrants treated bad is if your boss or manager has arrived at work all
dressed up then, you get there and you're all dirty but you got there a
bit late then when it's time to go he tells you that you not going to get payed,
you think that you wasted your time for nothing you get mad. Also if you're
an immigrant and you get payed the right amount for the time you worked
then you can say that you're treated well. So it depends on your manager
or boss.
