Can I use 'play hooky' this way?

- This year I have played hooky from work many times, and as a result, it would be a long shot for me to get promoted. (You would not use the word "for" before "many times.")

- He has often truanted from his duties, and might very well got sacked soon.

Although truant is used as a verb, i don't think either as a verb, a noun or an adjective, it is commonly used for anyone but a student. However, that does not mean that you can't use it to describe an employee. I would not use it for anyone but a student, but it is certainly not wrong.

Thank you very much for your clear answer.
