Push back or pushback? Both forms are correct, but they serve different parts of speech.
Write the verb as two words, with the regular past tense "push back" / "pushed back." Write the noun as one word: "pushback." In most workplace uses, this noun is uncountable: "some pushback," not "a pushback."

This spelling split can confuse even fluent, experienced professionals. The two forms look almost identical and sound identical in conversation. In speech, context shows whether the word is a verb or noun. In writing, spelling and word count reveal the grammatical difference. An error may stand out in a report or Slack message, making a skilled writer seem less careful.
"The vendor pushed back on the new contract terms."
Here, the word is a two-word verb with a regular past tense.
"There has been some pushback on the rollout plan."
Here, it is an uncountable, one-word noun, like "some feedback," not "a feedback."

Start the "Push Back" learning path →Two common errors, plus a third
Two mistakes are especially common. First, writers use the two-word verb "push back" where they need the noun "pushback." That noun presents resistance as a thing, not as the action of resisting. Second, they treat the usually uncountable noun as "a pushback." In general workplace English, use "some pushback" or "a concern" instead.
A third, less common error is the hyphenated form "push-backed." The correct past tense is "pushed back" because this phrasal verb changes normally. Its particle, "back," stays unchanged while the verb "push" carries the tense.
Use this "quick test" for the common workplace noun. If "a pushback" sounds odd, choose "some pushback." The article "a" is not a complete grammatical test, though. In "a pushback meeting," "pushback" modifies "meeting" rather than naming one unit of resistance. Some specialist fields use countable senses, but general workplace resistance is usually uncountable.
Why the split makes sense once you see the pattern
This split may feel random, but it follows a common English pattern. English often forms one-word nouns from two-word phrasal verbs. "Back up" becomes "a backup," while "break down" becomes "a breakdown." In the same way, "set up" becomes "a setup." "Push back" follows this spelling pattern. The two-word form describes an action, while the one-word noun names the resulting resistance.
Spelling and countability are separate grammatical issues. Related nouns do not necessarily follow one countability rule. For example, we say "we need more backup" but "there's been a breakdown in communication." In its common workplace sense, "pushback" names a general amount of resistance. It does not usually describe a single event that you can count.
When proofreading under time pressure, check the noun form separately. The verb's two-word spelling can easily become an unnoticed typing habit. A spellchecker may not flag "push back" where you need "pushback." Both forms are valid, so software needs grammatical context to identify the error.
