てはいられない・
てはいられない says that urgency, duty, limited time, or changing circumstances make it impossible to continue the current activity or state. The longer form with ばかり means that someone cannot keep doing only that when something else now requires attention.
Leaving the current activity behind
The construction looks back at an activity or state that is already continuing, then says circumstances no longer permit that continuation. It is therefore especially natural when the context gives a deadline, danger, responsibility, or necessary next step.
Urgency and a necessary next step
Notice how each example first establishes the pressure and then rejects continued delay or inaction.
What the longer form adds
てはいられない rejects continuing an activity or state. Adding ばかり highlights that the person has been occupied with that activity alone or to an excessive degree. The implied message is often: it is time to turn to something more necessary.

AnalyzeSimilar-looking patterns
てばかりいる describes someone as repeatedly or exclusively doing something; it does not itself say that the activity must stop. ないではいられない has the opposite direction: an inner feeling makes someone unable to avoid acting. By contrast, てはいられない says that circumstances make continued action or inaction untenable. Finally, わけにはいかない rules out an action because of responsibility or circumstances, without necessarily presenting it as an activity already in progress.
