Just want to gauge what people would do in my situation to see if I'm making a rational choice.
Home: Living with parents and grandparents, they are all retired and we have enough supplies to not have to leave home for at least a month. Most at risk if infected is 90 year old grandparent that also has diabetes and high blood pressure.
Work: Work has encouraged 1.5m distancing and frequent handwashing but due to the nature of work and teamwork needed for tasks, groups tend to work in close contact for many hours. I drive to work, whereas most others catch buses/trains. I have been rigorously handwashing but hygiene/distancing rules aren't really enforced so many coworkers don't follow it as much, especially ones that are young and are at low risk of death/do not have family that are at high risk, e.g. frequently joking about catching it so that they can take sick days off work (early 20s, live with partner/flatmates, they genuinely wouldn't mind despite news that some younger people become seriously ill too).
Situation: There's currently a very light workload due to reduced demand so work is happy for me to use annual leave (around 5 week's worth) then unpaid leave indefinitely. I am grateful to have a job at this time but I don't want to wait until it's too late to take action, especially since cases and deaths are starting to rise. There are bills and mortgage to pay but we are financially stable enough that we will be okay until the end of the year if none of us work and live the budget quarantine life (avoiding free delivery temptations!). After that, we would definitely need some source of income. I am unlikely to lose my position at work unless the company becomes bankrupt.
I am the only family member that needs to leave the house. I would be very regretful if I didn't take time off work when I am allowed to and made a family member seriously ill. If you were in my position, would you start taking leave?
