Hey everyone

I am in a bit of a situation. I have been offered a role in a supermarket in Hamilton and i have accepted the role. They have advertised the role with work and income although I am not sure if work and income is still operating especially in this field because even if they are how would they get someone to come in for an interview as we are in lockdown?
Next problem is, my immigration medical expired on 9 March, 2020. I called medical centre but they said they are not doing immiration medical during the lockdown. If i apply for visa without current valid medical, they probably would not even accept my application.
My current visa is still valid till 1 march, 2021 so this post has nothing to do with that.
Can someone please help
