Does this qualify as discrimination?

your boss is possibly racist or discriminating however do not let his harsh words let you down. Work is usually rough. However don't take his harsh comments as something to put you down. Just keep doing your work. However if your boss gets too much, it's always a good idea to take a break or if you can although i don't recommend it finding a different job is an option. then again it is possible that all this pressure is the "support" your looking for. So, that you don't feel too comfortable and always do your best. Some bosses use that as a strategy to keep their workers in tip-top shape. It has been proven to work especially with employees that have been just promoted if your boss has a military background it makes even more sense because that's the most common place you find this strategy especially the Marines. Ooh-Rah!!!
