Compete
“Compete” works when you mean pursuing the same goal against others rather than working with them. It is more precise than the original when that distinction matters.
Example: The two firms chose to compete for the contract rather than collaborate.
Work independently
Use “Work independently” for completing the work on your own instead of as part of a joint effort. Check the surrounding sentence because it is not necessarily interchangeable in every context.
Example: The analysts worked independently instead of collaborating on one model.
Act alone
“Act alone” emphasizes taking action without partners or collaborators. Choose it when that shade of meaning is the one you want to bring forward.
Example: The manager acted alone rather than involving the rest of the team.
Go solo
“Go solo” works when you mean choosing an informal, direct way to say that someone is working alone. It is more precise than the original when that distinction matters.
Example: After the partnership ended, she decided to go solo.
Work separately
Use “Work separately” for keeping tasks or efforts apart rather than combining them. Check the surrounding sentence because it is not necessarily interchangeable in every context.
Example: The departments worked separately instead of sharing the project.
Disengage
“Disengage” emphasizes stepping back from an existing joint effort or shared activity. Choose it when that shade of meaning is the one you want to bring forward.
Example: One partner chose to disengage from the joint initiative.
Oppose
“Oppose” works when you mean actively taking a position against another person, plan, or group. It is more precise than the original when that distinction matters.
Example: The groups opposed each other instead of collaborating on a compromise.
Resist
Use “Resist” for refusing to support or go along with a proposed joint action. Check the surrounding sentence because it is not necessarily interchangeable in every context.
Example: Several members resisted the proposed joint approach.
Compete against
“Compete against” emphasizes emphasizing rivalry with another person or group. Choose it when that shade of meaning is the one you want to bring forward.
Example: The two teams competed against each other rather than combining their efforts.
Withhold cooperation
“Withhold cooperation” works when you mean refusing to provide the help or coordination that collaboration requires. It is more precise than the original when that distinction matters.
Example: The supplier withheld cooperation during the investigation.
Refuse to cooperate
Use “Refuse to cooperate” for stating directly that someone will not work jointly with others. Check the surrounding sentence because it is not necessarily interchangeable in every context.
Example: The organization refused to cooperate with the review.
Act unilaterally
“Act unilaterally” emphasizes making or carrying out a decision without joint agreement. Choose it when that shade of meaning is the one you want to bring forward.
Example: The board acted unilaterally instead of seeking agreement from its partners.
Exclude
“Exclude” works when you mean keeping someone outside a group or shared process. It is more precise than the original when that distinction matters.
Example: The planning group excluded local representatives rather than collaborating with them.
Obstruct
Use “Obstruct” for making joint progress harder rather than helping it. Check the surrounding sentence because it is not necessarily interchangeable in every context.
Example: The rival group obstructed the process instead of helping it move forward.
Undermine
“Undermine” emphasizes weakening another person or group instead of supporting their shared work. Choose it when that shade of meaning is the one you want to bring forward.
Example: The criticism undermined the joint effort rather than supporting it.
Separate
“Separate” works when you mean moving people, tasks, or efforts apart rather than bringing them together. It is more precise than the original when that distinction matters.
Example: The project separated the two workstreams instead of bringing them together.
