Hello,
when I read the first phrase/sentence
Employees at a large computer company earn sick leave in one-minute increments depending on how many hours per month they work.
its meaning is just not clear to me.
No, I understand the meaning of each separate word (thanks to god).
But I do not understand mathematical meaning of this set of words, when they are taken together.
Therefore ( or "That is why" ), I did not even start to read it further.
