My thesis was done in industry environment, therefore in the acknowledgements I would like to thank all the people that helped me, but I do not know how I should call them. Colleagues does not sound right to me since I am not actually employed in that company although I spend there every day of the last 5 months.
Which is the right english word? (I am a non native english speaker, but I have to write my thesis in english). Moreover, which is the right word for my industry tutor? Shall I call it advisor (whereas my professor will be my supervisor)? Or is it better to say co-supervisor?
And lastly...shall I write both their name and surname or only the name?
