Since starting work, many years ago, I've always believed if you start work at 9, you come in at quarter to or just before so you can be ready to start. If you are held up for any reason, or have to drop kids off or whatever of course it's different. Of the two colleagues at work on the same level as me, one starts at 9:30 so comes in at any time between that time and quarter to ten, makes her coffee, eats her breakfast and is ready to actually work about ten or quarter past. The other one starts at 9 but comes in any time between quarter past 9 and quarter to ten. Neither have school age children. Maybe I'm in the one in the wrong?
