I have started a new job (UK) and have read the employee handbook, HR orientation etc. I've been doing the regular 9-5; always on time, productive despite being new etc.
I'm however starting to get the feeling that "40 hours per week" translates to 8h30m, not 8h; 8h of work + 30m lunch break. This is purely observational and was not stated anywhere in my contract / employee handbook / HR orientation etc.
I've been obliviously doing the 9-5 for a couple of weeks now, even saying "good morning" at 9 and "goodye" at 5 to my superiors (i.e. they can clearly see the times I enter and exit the office). I'm now in a situation where I'm pondering how to clarify the situation with my superiors; it might be that I'm not in the wrong at all (I know, I should have asked about this on day one, I just naively made the assumption this is how things work, seeing I was not briefed otherwise by anyone). I should also mention that we enter/leave the premises using a swipe card (which is, according to the employee handbook, a measure of security, not a measure of attendance).
How should I approach this?
