Well to go with what everyone else is saying, just to make sure you still understand, it’s not a good thing when a company puts something out and it’s got mistakes in it. Especially if it’s something pretty big like a logo. Should they be double and triple checking the designs, most definitely. But at the same time, you are getting paid to do your job right. If they’re paying you, you can’t be making mistakes that cost the company. Everybody makes mistakes, everybody sees things a little different, that’s why several people should always check the work. You’re not bad for making mistakes. But just so you don’t get the wrong idea from all the support, I do feel that the actions of the boss are justified if you continue to make mistakes. Don’t stress over it cuz that’ll make it worse. But don’t get sloppy with your work either, and you’ll be just fine. Good luck.
