I am so sorry your job is at risk and know what an awful feeling that is OP. Mine has been at risk several times over the past 10 years due to austerity measures and I fully expect it to be at risk again from January when contracts come up for renewal in March. I am however lucky that over lockdown my income hasn't been impacted.
What I really hate about this situation is that it pits ordinary people with genuine worries against each other.
The real issue here is that if we had a decent government who had been proactive in containing the virus and had put in place proper financial support for people being affected by this virus, and if we had a competent test and trace service in place, we wouldn't be in the position that we are in now.
You can be sure that if the virus overwhelms us again, hospitality will be affected either way, lockdown or not. Who is going to want to go out for their tea, or plan a big party, or whatever, if they are seeing friends and family falling ill.
Sadly the government have allowed the situation to get out of control again. Hospitals in the North West are already to capacity. We're now at the point where only a circuit break will help us. And SAGE seemingly agree.
If they had locked down early in the first place, we wouldn't have needed as long a lockdown as levels would have been much lower. It wouldn't have cost as much. I don't think we should make the same mistakes twice.
Instead of aiming your frustration at ordinary people who are also concerned about the situation we find ourselves in, aim it at the government. Write to your MP - tell them that hospitality businesses need proper financial support to survive. Tell them to get test and trace sorted. Tell them to make schools safer. Ask them why we still don't have effective border control policies for the virus - etc.
I wish you and your husband lots of luck and really hope that you keep your jobs and that things improve (for all of us) soon.
