I hate being late and usually am early, though on occasion I still arrive late. This is embarrassing but today I had a large coffee before leaving for work, and I had to get off the bus to use the bathroom. As a result I was 10 minutes late but had no other choice. I was fortunate enough to be able to walk the rest of the distance to work, but normally buses come every 15/20 minutes in my area. Note, I normally don't have a drink, but that day I needed extra caffeine. Right now we are being trained and are in a computer lab with an instructor. The instructor didn't say anything to me but another student told me he was mad. I made a point to apologize and he asked what happened and I told him.
He had also asked to send him a text message if you are going to be even 1 minute late.
What do you say to your manager/instructor when you're late? Do you just say "sorry I was late" or do you give a reason too even if not asked? Also do you wait for a minute to be alone with them? I don't want to interrupt the whole class with my story.
If the manager/instructors wants to know even if you're going to be 1 minute late, sometimes it's hard to know with that much detail in advanced. Is it better to message that you will be late, or is it better not to as not to leave a paper trail as you may be on time?
How often and by how much can one be reasonably late? Obviously the goal is to always be on time though this isn't always possible.
I've only been late once before because a traffic accident. It may also be worth noting that since the computer lab is used before our group, we aren't allowed to arrive early.
This is different than my last job where the boss was ok with plus or minus 10 minutes from official start time and I'm having trouble adjusting. For example the instructor gets mad if someone goes to refill their water bottle shortly after the lunch break and says they are late.
The next day the instructor pulled people out of the room one by one to talk to them. I was one of them. It was about being late. He informed me I had been late 2 times and if it happened again during training (which is 7 weeks long) I would get written up and talked to. I confirmed that 1 minute after the start is considered late and he said yes. He counts every time, for example when I was late because their was a traffic accident I couldn't get around and preemptive sent him a message.
