I work as a software engineer in a relatively nice office, with several benefits and a great working environment.
Sometimes I decide to work overtime to get some things done before leaving for the day, and so do some of my colleagues. These overtime hours get registered on the company's system, but do not count towards my paycheck.
My contract specifies that I must meet a certain amount of hours each month, which I do and then some more. I've recently asked my colleagues about using my overtime hours to leave early sometimes, which would help me sort things out on a personal level as well as managing meetings on my freelance jobs.
Their response was that it technically is possible, but looked down upon by the higher ups. None of them do this either, not because they can't, but because they don't want to put up with our bosses.
My question, is it okay to approach this with higher ups? how can I do so?
I'd like to make use of this benefit, but at the same time I don't want to damage my current position here as I really like this company. Hence the question.
