Min chef siger, at ansvar uden respekt hurtigt skaber problemer på kontoret.

Because chef is a common-gender noun in Danish: en chef.

Danish possessives agree with the noun that follows:

• min
  • common-gender singular noun
• mit
  • neuter singular noun
• mine
  • plural noun

So you get:

• min chef
• mit kontor
• mine chefer

Also, min does not tell you whether the boss is male or female. It only matches the grammatical gender of chef.

Yes. In Danish, chef usually means boss, manager, or supervisor.

If you mean a cook/chef in the English sense, Danish normally uses kok.

So:

• chef = boss/manager
• kok = cook

A native English speaker often notices this right away because the spelling looks familiar, but the everyday meaning in Danish is different.

Siger is the present tense of at sige.

Danish present tense is usually formed by adding -r to the infinitive:

• at sige → siger

And unlike English, the verb does not change for different persons:

• jeg siger
• du siger
• han/hun siger
• min chef siger

So siger simply means the verb is in the present tense.

Here, at is a conjunction meaning that.

It introduces the clause after siger:

• Min chef siger, at ...

In English, that is often optional:

• My boss says that ...
• My boss says ...

In Danish, at is very commonly kept, especially in normal written language.

This is about word order in a subordinate clause.

After at, Danish does not use normal main-clause verb-second word order. Instead, the clause has a more regular subordinate structure.

Here the subject is:

• ansvar uden respekt

Then comes the adverb:

• hurtigt

Then the finite verb:

• skaber

So the pattern is roughly:

• at + subject + adverb + verb + object

That is why hurtigt skaber is natural here.

You may also see other adverb placements in Danish depending on style and emphasis, but in an at-clause, placing the adverb before the finite verb is very common.

Because both are being used in a general, abstract sense.

In Danish, abstract nouns often appear without an article when you talk about them in general:

• ansvar
• respekt
• kærlighed
• frihed

So ansvar uden respekt means responsibility in general, not a specific responsibility and a specific respect.

If you were talking about something specific, you could use an article or another determiner:

• et ansvar
• respekten
• den respekt

But here the sentence is making a general statement, so no article is needed.

Because problemer is an indefinite plural.

In Danish:

• singular indefinite often has an article: et problem
• plural indefinite has no article: problemer
• plural definite adds an ending: problemerne

So:

• skaber et problem = creates a problem
• skaber problemer = creates problems
• skaber problemerne = creates the problems

This sentence uses the indefinite plural because it means problems in general.

Because på kontoret is the normal idiomatic Danish way to say at the office or in the office environment.

Danish often uses på for workplaces and institutions:

• på kontoret
• på skolen
• på hospitalet

By contrast, i kontoret would sound more like inside the office room physically, and is less natural here.

So:

• på kontoret = at the office / in the workplace setting
• i kontoret = inside the office room

Kontoret is the definite singular form of kontor.

The noun is:

• et kontor = an office

Its definite form is:

• kontoret = the office

That happens because kontor is a neuter noun, so the definite ending is -et:

• et kontor → kontoret

This is one of the basic Danish noun patterns:

• common gender: en bil → bilen
• neuter: et kontor → kontoret

Not always.

In modern Danish, writers may use:

• comma before a subordinate clause
• or no comma before it

So both of these can be accepted depending on the comma style:

• Min chef siger, at ...
• Min chef siger at ...

Many people still include the comma, especially in more formal writing, so the version in your sentence looks completely normal.
