I work on a 250 acre country park and have been told I am sometimes going to have to work alone .is there a law about working alone on such a large site also dealing with the public

Forest rangers may be in larger areas working alone.

County sheriff deputies often work in large areas with no other officers near.

What is your issue or problem working alone

I work in england uk and have just lost my driving licence and my employer is saying I can't do the job without one so am looking for ideas to keep my job and thought maybe working alone was against the law in such a big popular park .
