Present Perfect is commonly used in everyday speech – in professional context, it is particularly suitable for example for job application process to talk about one’s achievements and experience.

the perspective of the present.

Causatives

These are structures to talk about situations when somebody causes another person or thing to do something. Simply speaking, things get (not) done, even though it is not you who (don’t) do them. It is quite useful when talking, for example, about delegating work within corporate hierarchy.

A causative structure can be active, i.e. we know who delegates to whom:

Mr. Headhunter had Jennifer write the candidates’ evaluations. (He told her to write it.)

I had our IT guy fix my crashed computer. (I called him to do it.)

Or it can be passive, when we do not know the doer, or they are unimportant, obvious etc.:

My boss had a new computer installed in his office. (Somebody competent installed it.)

Every other Monday, we have our company cars serviced and washed. (People in the garage do it.)

There are some other causative forms, let us mention the following:

Our boss is wonderful. He lets us take our dogs to the office. (He allows it.)

The management make us wear smart clothes at work all week. It’s rather uncomfortable.

(They force/compel us to do so, we’d rather wear something casual.)

Remember

As you can see from the examples, in the above mentioned causative structures the causative verb (have, make, let) is followed by infinitive without to.
