Where is the line between deadline and overtime?

Question

Project management

Agency, 8 employees. I'm in charge of the frontend.
This is the situation at work (it’s my first, so I judge the organization of work only by reading articles and other material): I constantly sit up at work for 3-4 hours, sometimes I work on weekends, because the manager says that new changes have appeared on projects and you need to quickly fix them + add 4-5 projects to this, which I do in parallel. Can all "urgent edits" be attributed to a "deadline" or is it just regular work for which I have the right to demand overtime?

Answer 1

Deadlines turn into overtime in the same way as Cinderella's carriage into a pumpkin - as soon as the clock strikes the end of the 9th hour of the working day -> overtime begins.

Answer 2

Formally:
According to the law, there is no concept of "deadline".
But the concept of "overtime" - is.
In fact:
And not according to the law - how to agree on how satisfied you are with staying at work, how sure you are that you will not be trampled if you do not stay, etc., etc. considerations.
