assume to

Are these sentences correct:

[color=red]1-I assume to get a promotion next month.
(Meaning: I assume that I will get a promotion next month.)

[color=red]2-I assume to have to do a lot of work next week.
(Meaning: I assume that I will have to do a lot of work next week.)

[color=red]3-I assume to have trouble with the new employee.
(Meaning: I assume that I will have trouble with the new employee.)

Gratefully,
Navi.

They’re all incorrect. "I assume to have…’ is not valid.

I assume I will get a promotion …
I assume I will have a lot of work to do …
I assume I will have trouble with …

Other nouns/pronouns can be substituted for ‘I’.
