Grindr is a US company, even if it weren't the employees in question are in the US, so subject to US employment law, which is what my comment revolves around.
The NLRB site explicitly states that striking is a legal action employees can take ('“Employees shall have the right. . . to engage in other concerted activities for the purpose of collective bargaining or other mutual aid or protection.” Strikes are included among the concerted activities protected for employees by this section. Section 13 also concerns the right to strike'[1], 'Employees at union and non-union workplaces have the right to help each other'[2])
The NLRB site explicitly states that firing an employee due to them striking is illegal ('You cannot be fired for participating in a protected strike or picketing, depending on the purposes and means of the strike action.'[3])
The NLRB site, and numerous law firms (on both sides) seem to say that you can't just "not work", there is some formal process.
If you want to go on strike you should talk to either an employment attorney, or your union if you're in one.
I am genuinely curious, if you're down voting my comment, I'd love to know why.
