Quit my job

I thought a bigger weight would be lifted off my shoulders doing this.. but alas.. it didn’t! I have the board hunting me down and members trying to get my to stay, the boss has called 3 times now offering me more money to stay and I really don’t want to but I feel so guilty that I feel like I could be swayed into going back:(
I quit because the sanitary conditions in this kitchen are so GROSS!!! like so bad.. I would never eat there- and here I was serving food outta there – breaking my own rules. “If I won’t eat it- I won’t serve it” I always spouted… then I figured that if I cleaned and made things better it would be ok.. wekk for 5 weeks it was a friggen nightmare- no one follows food safe, nothing- the last straw was on Monday when I walked in there to find the PLUNGER from the MENS BATHROON in my KITCHEN that they ised in the SINK!!!!!!!!!!! EWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW!!!!! The scary thing was- no one saw this as a problem- including my boss who shrugged at me and walked away. I nearly walked out but I figured I couldn’t let ppl get sick so I spent three hours bleaching everything I could get my hands on – I quit later that night and he was a jerk about it and got mad and left for the day.
Now everyone is trying to get me to stay/come back – the board wants me to run the place and I can’t! I just can’t! I have otehr commitments to me and my family and as bad as I want to for everyone else’s sake… besides 2 of the cooks think I am too much of a pain in the ass and think my “cleanliness” isn’t nessesary and they like the boss so I figure they will quit after he gets fired then there will be just me to fill 22 shifts a week. I mean o could pull it off.. but i gave up my cafe so I didn’t have to do this kinda thing anymore. I just wanted to work my 8 hours a day and go home.. :(
