go over (something)

"Going over" something means discussing or reviewing it.

You can "go over" things like:

• plans
• lists of rules
• someone's work

You can "go over" things that have already been done or discussed. You can also "go over" things that are new. For example, say this to someone who's going to participate in your wedding ceremony:

Let's go over what you're supposed to do on the day of the ceremony.

(an organization's) policy on (a topic)

Companies and other organizations have "policies". A "policy" is like a rule. The difference is that the word "rule" sounds a little more strict and unbreakable.

You can talk about an organization's different policies using the phrase "policy on __":

What's our policy on customer complaints?

You can also talk about a "___ policy":

They have a strict cancellation policy.

Policies can apply to the members of an organization, as well as to other people, like customers.

sick days

"Sick days" are days that you stay home from work or school because you get sick or injured:

I took a sick day.

You can talk about the number of days that employees or students are allowed to take off:

How many sick days do we get here?

This is a casual phrase. A more formal phrase is "sick leave".
