Multiple TRUE values on a SWITCH TRUE(); Function

Hello PBI Community!

I have a SWITCH function that evaluates with the value in one particular column of my table is true (name of an employee) to call a specific Measure as Value for a visual. This works great and all, but when no name is selected, I'd like call a different measure, but the function doesn't work:

 SWITCH( TRUE();
VALUES('All'[COLAB]) = "Employee 1"; [# Total Hours Worked by Employee 1];
VALUES('All'[COLAB]) = "Employee 2"; [# Total Hours Worked by Employee 2];
VALUES('All'[COLAB]) = "Employee 3"; [# Total Hours Worked by Employee 3];
VALUES('All'[COLAB]) = "Employee 4"; [# Total Hours Worked by Employee 4];
VALUES('All'[COLAB]) = "Employee 5"; [# Total Hours Worked by Employee 5];
VALUES('All'[COLAB]) = "Employee 6"; [# Total Hours Worked by Employee 6];
VALUES('All'[COLAB]) = "Employee 7"; [# Total Hours Worked by Employee 7];
[_Sum Spend Time by All]
)

This works with a table that has all these names and every time I select one name on the table, the line graph that containes the aboe function work nicely, but wehn no name is selected it won't call the "[_Sum Spend Time Total (Decimal)]" measure you can see in the last line. I believe this is because the function sees all the values as being true. Is there any way to make this work? 

Thanks in advance to this great Community!

Best and stay Safe
