Another structure making use of the combined て and は particles is
ては～ては. This grammar pattern highlights that the actions of (A) and (B) are continuously being repeated and can be interpreted as ‘doing (A) and (B) repeatedly’. The (A) and (B) actions will often be things that contrast each other in some respect, such as starting and stopping, walking and running, going forwards and then backwards, etc.
ては～ては will be used with verbs in the て-form, so will occasionally appear as では.

仕事（しごと）ではミスしては怒（おこ）られ、怒（おこ）られてはミスをする。毎日（まいにち）この繰（く）り返（かえ）しだから仕事（しごと）を辞（や）めようと思（おも）う。
At work, I make a mistake and get yelled at, get yelled at and make a mistake. This repeats every day so I am thinking of quitting my job.
The abbreviated versions of
ちゃ and
じゃ may also be seen with the grammar point, but it may be considered unnatural if the same abbreviation is not used both times. This is mainly due to the level of formality being required to stay the same within sentences.

Caution -
ては may sometimes appear only once, without any change to the meaning of repetition. This is usually when there is some indication in the rest of the sentence that the action is something that is being repeated over and over.
