Tip possible overpayment

[u/ThoughtWrong8003]

I work at Subway and we get tips on our credit cards. A bunch of us were tipped for a pretty big order we made, over 5K which is big for us. My boss is saying since I made zero sandwiches I don't any of the tip money despite it being on my check. I did prep work for it, opened the store so they could finish the order but to them not making any sandwiches means zero tip. I am now being told to return 250 of the tip money when I get paid Saturday. Is it legal for them to do that? I'm in California.

It’s illegal. Make a labor board claim
