If you don't want to be stuck while a colleague does changes that conflict with what you're changing then yes, you need branching.

You don't need branching for this.

If 2+ people are working on the same file which might result into a conflict, you can either: - handle the conflict as soon as you merge your branches somewhen in the future or - handle it when trying to commit your change to head

Only difference is whether you handle the conflict now, or in the future.

You need to communicate with your colleagues to coordinate your work.
