Calling out once is life. Calling out every Friday is a reputation.

One absence is an event and a repeated one is a pattern, and managers mostly notice the second. Everybody gets ill or has a day where it is genuinely impossible, and a decent workplace absorbs that. What gets noticed is the shape: the same day every week, always the busy shift, always at the last minute.

Look at your last two months of shifts and see whether there is a shape. If there is, the fix is usually the schedule rather than your character. Ask for the Friday off properly and in advance, which works better than calling in.
