Welcome to the real bissines world ..
If they don't wont you any more you can't take the menu with you,is created for that restaurant ..
Same situation is gong on in the resort where I a work now .. Management keep trying to replace me ... Because I start asking for my rights.. So what I did
I ask the management for 3 days off. To see how my kitchen will operate without a chef .. Only with station cooks and a "pastry chef " who don't know what is tempering chocolate...
