L Permit Dependent (Zurich)

Hello,

I hold L permit dependent visa with authorization to work and currently working in Zurich. After my spouse deregisters , is it possible for me to continue working here?
My visa is till march Protected content .
If yes, then what happens after march Protected content , Can I renew it based on my job here as I am a permanent employee with no contract duration mentioned on the contract when I had joined.

Thanks,
