My last work day inof thise year

Sounds more natural and intuitive to use ‘of the’ instead

Today is my last day inof thise year.

‘is’ is required here for the sentence structure to be grammatically correct.

I look around me i. I see lot of empty work stations which are empty.

This works best as 2 sentences. ‘I’ needs to always be capitalised, even if it’s not at the beginning of a sentence.

At the moment only iI’m working, because themy coworkers are on holiday.

‘I am’ or ‘I’m’ is grammatically correct. Coworker has to be plural because there are many work stations so many coworkers.

Unforuntlety iI should be on holiday, but iI arrived here from 2 months ago, so unfortunately my holidays awere overused up on my last job.

Where you place ‘unfortunately’ changes the meaning of the sentence. I changed where it was so it’s unfortunate that you don’t have holidays, not that you should be on holiday.

Time is always plural when it has been more than one so it is ‘2 months’.

It is the reason why iI’m working now.

When it’s singular, it is always ‘I am’ or ‘I’m’.

Today is my last day of work in this year.

When I look around me i, I see lot of work stations which are empty.

At the moment, only iI am working, because themy coworkers are on holiday.

Unfortuntlety iately, I should be on holiday, but iI arrived here from 2 month ago, so myI can't take holidays are over on my last jobt my new job yet.

IThat is the reason why iI am working now
