How it works

Why are the two people wearing the same clothes? Look at the notice to find what the shop requires.

「ことになっています」 describes an established rule. Wearing a uniform is a rule the shop has already set.

It can also describe an established customary practice. The point is an existing convention, not just a personal habit.

It can also describe an arrangement fixed by a plan. The arrangement is already decided when you speak.

Use the verb’s dictionary form: 「着る」 + 「ことになっています」, not 「着ます」.

Here, 「ています」 means the rule is still in effect. It does not mean the action is happening right now.

In the example, “three days a week” is an agreed work schedule. It does not simply mean that this is what the person often does.
